Rikard Falkeborn ddcbed21d6 std.cfg: Add podtype char8_t (#2257)
c++20 introduced type char8_t.

From https://en.cppreference.com/w/cpp/language/types:

char8_t - type for UTF-8 character representation, required to be large
enough to represent any UTF-8 code unit (8 bits). It has the same size,
signedness, and alignment as unsigned char (and. therefore, the same size
and alignment as char and signed char), but is a distinct type.
