    include/stdbit.h: declare size_t, (u)int*_t, and (u)int_least*_t
    
    These are required by ISO/IEC 9899:2024 § 7.18.1 ¶ 1 but were forgotten
    in my initial work.
    
    The current approach leaks intptr_t, uintptr_t, intmax_t, and uintmax_t
    through <sys/_stdint.h>.  This could be avoided using a more complicated
    approach if desired.
