Niels Lohmann dd3ed1ef86 Check and sanitize strings out of line ...

The string writers kept the string_t that holds a sanitized copy for the other
error handlers in the function that also has the fast path for the default
one, so that every string paid for its construction check, a stack frame with
a stack protector under GCC, and the registers saved for the slow path.

The slow path is now a function of its own that the fast path does not call.

Instructions per call (Linux, GCC 13, thousands), to_ubjson: twitter 3867 -> 3274, 20000 small objects 20981 -> 17901; to_bjdata: twitter 3873 -> 3281, 20000 small objects 21001 -> 17921; to_msgpack: 20000 small objects 18342 -> 15922.
