[libc][test][stdbit] fix -Wimplicit-int-conversion ( #126616 )
...
When cross compiling the libc-stdbit-tests, the existing tests trigger numerous
instances of -Wimplicit-int-conversion. The truncation of these implicit
promotions is intentional.

[libc] Fix use of cpp::numeric_limits<...>::digits ( #102674 )
...
The previous change replaced INT_WIDTH with
cpp::numberic_limits<int>::digits, but these don't have the same
value. While INT_WIDTH == UINT_WIDTH, not so for ::digits, so
use cpp::numberic_limits<unsigned int>::digits et al instead for
the intended effects.

[libc] Use cpp::numeric_limits in preference to C23 <limits.h> macros ( #102665 )
...
This updates some code to consistently use cpp::numeric_limits,
the src/__support polyfill for std::numeric_limits, rather than
the C <limits.h> macros. This is in keeping with the general
C++-oriented style in libc code, and also sidesteps issues about
the new C23 *_WIDTH macros that the compiler-provided header does
not define outside C23 mode.
