Add the StrictBinaryUTF8 and DeleteDeprecatedFunctions Meson options

JSON_StrictBinaryUTF8 (#5741) and JSON_DeleteDeprecatedFunctions (#5755)
arrived with develop but were missing from the Meson build and the
pkg-config file, so check_build_options failed. Both Meson options
default to false and add JSON_STRICT_BINARY_UTF8=1 and
JSON_DELETE_DEPRECATED_FUNCTIONS=1 to the dependency, the pkg-config
file, and the generated CMake target; CMake's pkg-config file now
carries both definitions too. The ci_meson_install job sets and checks
them in its non-default install.
