After base 966fb94cb3, this revert is no longer necessary: stdint.h
will unconditionally define macros such as `SIZE_MAX`, `UINT64_C`, and
others.

This partially reverts upstream libc++ commit aa7f377c965c:
[libc++] Remove libc++'s own stdint.h and locale.h (#107436)
These headers are not doing anything beyond the system or compiler
provided equivalent headers, so there's no real reason to keep them
around. Reducing the number of C headers we provide in libc++ simplifies
our header layering and reduces the potential for confusion when headers
are layered incorrectly.
The problem is that libc++'s own `stdint.h` _does_ do something: it
defines `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` before
including the system `stdint.h`, causing the latter to expose macros
like `SIZE_MAX`, `UINT64_C`, and others.
If the `__STDC_LIMIT_MACROS` and `__STDC_CONSTANT_MACROS` macros are not
exposed, C++ programs compiled for standards before C++11 can fail with
errors due to those macros not being available.
