stdlib: Implement mbrtoc8, c8rtomb, and the char8_t typedef.
This change provides implementations for the mbrtoc8 and c8rtomb functions adopted for C++20 via WG21 P0482R6 and for C2X via WG14 N2653. It also provides the char8_t typedef from WG14 N2653. The mbrtoc8 and c8rtomb functions are declared in uchar.h in C2X mode or when the _GNU_SOURCE macro or C++20 __cpp_char8_t feature test macro is defined. The char8_t typedef is declared in uchar.h in C2X mode or when the _GNU_SOURCE macro is defined and the C++20 __cpp_char8_t feature test macro is not defined (if __cpp_char8_t is defined, then char8_t is a builtin type).
