clang (#152724)
Define `_LIBCPP_HAS_C8RTOMB_MBRTOC8` to `1` if compiling with clang.
Some tests involving functionality from `uchar.h`/`cuchar` fail when the
platform or the supporting C library does not provide support for the
corresponding features. These have been xfailed.
This patch will enable the adoption of newer picolibc versions.

Picolibc is a C Standard Library that is commonly used in embedded
environments. This patch adds initial support for this configuration
along with pre-commit CI. As of this patch, the test suite only builds
the tests and nothing is run. A follow-up patch will make the test suite
actually run the tests.

These test cases were fixed with AIX 73TL1, and are currently passing on AIX machines with that fix. This fix has also been backported to the 7.2 service line. These were tested on a machine with AIX 7.2 TL 5 SP4 installed.

This has been done using the following command
find libcxx/test -type f -exec perl -pi -e 's|^([^/]+?)((?<!::)size_t)|\1std::\2|' \{} \;
And manually removed some false positives in std/depr/depr.c.headers.
The `std` module doesn't export `::size_t`, this is a preparation for that module.

This change implements the C library dependent portions of P0482R6
(char8_t: A type for UTF-8 characters and strings (Revision 6)) by
declaring std::c8rtomb() and std::mbrtoc8() in the <cuchar> header
when implementations are provided by the C library as specified by
WG14 N2653 (char8_t: A type for UTF-8 characters and strings
(Revision 1)) as adopted for C23.
A _LIBCPP_HAS_NO_C8RTOMB_MBRTOC8 macro is defined by the libc++ __config
header unless it is known that the C library provides these functions
in the current compilation mode. This macro is used for testing purposes
and may be of use to libc++ users. At present, the only C library known
to implement these functions is GNU libc as of its 2.36 release.
