rG72609bb2bb25: uchar.h: add char8_t
rGf0e541118c37: uchar.h: add char8_t

Summary

A type similar to char16 and char32_t, for compliance with C23.
The related type atomic_char8_t is added to stdatomic.h.
As char8_t is always unsigned char, I've skipped adding __char8_t.
This can be added, too, if desired.
