Tests: skip the parse() allocation sweep with MSVC iterator debugging

With _ITERATOR_DEBUG_LEVEL > 0 (MSVC STL debug builds, clang-cl), containers allocate inside noexcept functions, so a failing allocation terminates the program: "test case CRASHED: Terminate handler called" in the sax_parse subcase of #5985. The sweep test of #6000 has the same guard. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
json_view: no constant operand in the number dispatch (MSVC C4127)

 - **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: `std::string` for strings, `int64_t`, `uint64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. However, you can template the generalized class `basic_json` to your needs.

- **Speed**. There are certainly [faster JSON libraries](https://github.com/miloyip/nativejson-benchmark#parsing-time) out there. However, if your goal is to speed up your development by adding JSON support with a single header, then this library is the way to go. If you know how to use a `std::vector` or `std::map`, you are already set. The [performance](https://json.nlohmann.me/features/performance/) page shows how to get the most out of the library.

-```cpp
-#define JSON_RECURSION_DEPTH_LIMIT /* value */
-```
-
-This macro sets how many nesting levels the operations that walk a value recurse into on the call stack. Beyond that,
-they continue with an explicit stack on the heap. The value is an integer constant from `0` to `254`; the default is
-`128`.
-
-The operations are copying a value, comparing two values, serializing with [`dump`](../basic_json/dump.md) or
-[`operator<<`](../operator_ltlt.md), hashing with `std::hash`, [`merge_patch`](../basic_json/merge_patch.md),
-[`update`](../basic_json/update.md) with `merge_objects`, [`diff`](../basic_json/diff.md),

-[`to_bjdata`](../basic_json/to_bjdata.md), and [`to_bon8`](../basic_json/to_bon8.md). They share this one limit; none
-has
-a limit of its own. Recursing is the fastest way to walk a value, but a value nested deeply enough would exhaust the
-call
-stack, so the library recurses only as far as the limit and finishes the levels below with an explicit stack. This is
-what makes all of them safe for untrusted input
-(see [Nesting depth](../../features/parsing/untrusted_input.md#nesting-depth)). Parsing, the binary readers,
-[`flatten`](../basic_json/flatten.md), [`unflatten`](../basic_json/unflatten.md), and
-[`to_bson`](../basic_json/to_bson.md) always use an explicit stack and do not depend on the macro. The lockstep
-comparison of two [`json_view`](../basic_json_view/index.md) documents has a fixed bound of its own, 48 levels,
-and does not depend on it either.
-
-The call stack that these operations need grows with the limit: roughly *a few kilobytes plus a cost per level times the
-limit*, where the cost per level is up to about 2.3 KiB in an unoptimized and up to about 0.5 KiB in an optimized build
-(see [Stack needed](#stack-needed)). The default of `128` levels is tuned for threads with ordinary stacks of a few
-hundred kilobytes or more. Set a lower limit if your threads have small stacks (RTOS tasks, fibers, threads of the musl
-C
-library, which has a default stack of 128 KiB), or a higher limit to trade stack for speed on deeply nested values.
-
-The macro changes only how much stack is used and how fast the operations are. It never changes a result: every
-operation returns the same value for every setting of the limit, for values nested less deeply than the limit as well as
-for values nested more deeply.
-
-## Default definition
-
-The default value is `128`.
-
-```cpp
-#define JSON_RECURSION_DEPTH_LIMIT 128
-```
-
-When the macro is not defined, the library defines it to its default value.
-
-## Notes
-
-!!! note "Allowed values"
-
-    The value must be an integer constant expression from `0` to `254`; any other value (a negative number, a number
-    above `254`, a floating-point number such as `254.0`, or `true` or `false`) is rejected at compile time with an
-    error message that names the macro. A character of any character type (`'a'`, `L'a'`, `u8'a'`, ...) is rejected,
-    too, although it is an integer.
-
-    - `0` is allowed, and means that every operation uses its explicit stack from the first level on and no operation
-      recurses over the nesting of a value at all. That needs a constant amount of call stack (at most 16 KiB in the
-      measurements below, for a value nested 20,000 levels deep) and is the setting for tiny stacks, at the price of
-      speed (see [Speed](#speed)).
-    - `254` is the largest allowed value. Copying a value and comparing two values (with `<=>`, or with the operators on
-      objects and arrays of a custom type) cannot pass the depth down as an argument, because the signatures of the
-      copy constructor and the operators are fixed. They count the levels they have descended into in a variable of type
-      `#!cpp std::uint8_t` that exists once per thread (see [`JSON_NO_THREAD_LOCAL`](json_no_thread_local.md)). Only
-      the levels that are descended into are counted, so the count never exceeds the limit, not even when user code (a
-      copy constructor of a custom base class, say) copies a value while a copy is going on. A byte holds `255` at
-      most, and the limit stays below that, so that the count cannot wrap around. (More levels would hardly be
-      useful: `254` levels need up to 576 KiB of stack in an unoptimized build already, twice as much as the
-      default.)
-
-### Stack needed
-
-The tables show the smallest stack that an operation needs, in KiB, at several limits, on a value that is nested
-more deeply than the limit (limit + 10 levels). Each cell shows the result for Clang (Apple clang 21) and for
-GCC 16, separated by a slash; both measured on macOS with arm64, compiling in C++20 mode. The operations run in a
-thread whose stack has the size given, and are not given any stack that they do not need: the value is built, and
-the result destroyed, outside of that thread. Stacks can only be set in steps of 16 KiB (the page size), so `16`
-means "16 KiB or less". A row stands for all operations listed; the table shows the largest value among them.

-With a limit of `0`, every operation in the tables ran in a 16 KiB stack at `-O0` (Clang and GCC), on a value nested

-16 KiB or less at every limit.
-

-(1.3 KiB with GCC), and 0.1 to 0.5 KiB for most other operations at `-O0`; and 0.5 KiB or less at `-O2`. The numbers
-come from the difference between the limits `128` and `254` in the tables, so they are rough: other compilers,
-other targets (the frames of x86-64 code are about as large), other standard libraries, `JSON_DIAGNOSTICS`, and
-sanitizers change them. Measure with your own tool chain (see the example below) rather than relying on the tables.

-The table shows the time of copying a value (including destroying the copy), of `==` on two equal values, of `dump`, and
-of `std::hash` for several limits, relative to the default of `128` (`1.00` means the same time; more is slower). It was
-measured with Clang 21 at `-O2` in C++17 mode on macOS with arm64, as the best of seven runs of each setting (two
-rounds, best of both). The documents are ordinary JSON files that are nested 7 (`canada.json`), 8
-(`citm_catalog.json`), 10 (`twitter.json`), and 2 levels deep (`jeopardy.json`); the other values are one array or object
-with one member per level, nested 1,000 and 100,000 levels deep. The absolute time at the limit `128` is given in the
-third column. Differences of up to about 0.1 are noise: a different limit changes the layout of the compiled code, and
-timings of the same binary vary by about as much. The slow columns (limits 0 and 1) vary more: repeating `std::hash` on
-`canada.json` gave 1.27 to 1.30 for limit 0 and 1.4 to 1.9 for limit 1, so read the cells of those two columns as
-accurate to about 0.3.

-The results are as follows.
-
- A limit of `16` or more does not change the speed of ordinary documents (differences are within noise), because they
-  are not nested more deeply than that anyway. A document nested more deeply than the limit is walked partly with the
-  explicit stack.
- A limit of `0` or `1` makes the operations on ordinary documents 1.1 to 2.4 times as slow, because even their first
-  levels are handled with the explicit stack. The slowdown is largest for `==` on a document of many small containers
-  (`canada.json`: 2.4 times) and for copying (up to 1.8 times).
- For values that are nested far more deeply than any limit (1,000 and 100,000 levels deep), the limit makes no
-  measurable difference: almost all of the levels are handled with the explicit stack for every setting.
-  Raising the limit gains nothing for them, and lowering it costs nothing.
-
-!!! note "Other macros"
-
-    - With [`JSON_NO_THREAD_LOCAL`](json_no_thread_local.md) defined (or for Clang targeting MinGW, where the library
-      defines it by itself), copying and comparing never descend, so for them the limit does not matter. The other
-      operations still recurse as many levels as the limit says. The range of the limit is the same.
-    - The macro is not part of the [ABI tag](../../features/namespace.md), as `JSON_NO_THREAD_LOCAL` is not, and it is
-      not undefined at the end of `json.hpp`.
-
-!!! warning "Use the same value in every translation unit"
-
-    All translation units of a program that include the library must define the same value. Otherwise, the program
-    violates the One Definition Rule: the function `nlohmann::detail::recursion_depth_limit()` and all the functions
-    that use it are defined differently in different translation units. Which limit a call uses then depends on which
-    functions the compiler inlined (an inlined copy uses the value of its own translation unit) and which out-of-line
-    copy of each remaining function the linker kept, which is not specified. A function compiled with one value can
-    call a function compiled with another, so a single operation can mix both limits.
-
-    Mixing values cannot corrupt the byte per thread that counts the levels of copying and comparing: each limit
-    is at most `254`, and all of them stop counting at their own limit, so the count never exceeds `254`, whichever
-    translation unit's definition runs. The counter exists once per thread and `basic_json` specialization, and is
-    shared by all translation units. Nor can mixing values change any result, as no result depends on the limit. What
-    changes is how much stack is used and how fast the operations are. Nevertheless, avoid it: the program has undefined
-    behavior as far as the C++ standard is concerned.
-
-## Examples
-
-??? example "Example: lower the limit"
-
-    The example nests an array 5,000 levels deep. With the limit set to 16, the library recurses over the first 16
-    levels
-    and over the rest uses an explicit stack. The results are those of the default limit.
-
-    ```cpp
-    --8<-- "examples/json_recursion_depth_limit.cpp"
-    ```
-
-    Output:
-
-    ```
-    --8<-- "examples/json_recursion_depth_limit.output"
-    ```
-
-??? example "Example: find out how much stack an operation needs"
-
-    The program runs `dump()` on a value nested `depth` levels deep in a thread with a stack of `kib` KiB. Compile it
-    with the options and the limit that you use, e.g. `-DJSON_RECURSION_DEPTH_LIMIT=64`, run it with `depth` set to the
-    limit plus 10 and decreasing values of `kib` (the stack size must be a multiple of the page size, often 4 or 16
-    KiB),
-    and note the smallest stack with which it still finishes. That is how the tables above were measured.
