Revert 00bee6fcd77f, which partially reverted libc++ commit aa7f377c965c

After base 966fb94cb357, this revert is no longer necessary: stdint.h
will unconditionally define macros such as `SIZE_MAX`, `UINT64_C`, and
others.

Partially revert libc++ commit aa7f377c965c, restoring stdint.h

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.

Fix buildworld with gcc 12 after llvm-19 import

Unfortunately gcc 12's is not yet capable of compiling all of libc++
19's C++23 code, which results in errors similar to:

/usr/src/freebsd/src/contrib/llvm-project/libcxx/include/__algorithm/ranges_contains.h:41:3: error: 'static constexpr bool std::__1::ranges::__contains::__fn::operator()(_Iter, _Sent, const _Type&, _Proj)' must be a non-static member function
41 | operator()(_Iter __first, _Sent __last, const _Type& __value, _Proj __proj = {}) {

48 | operator()(_Range&& __range, const _Type& __value, _Proj __proj = {}) {
| ^~~~~~~~

Until we can get rid of gcc 12, work around this by making it compile
libc++ in C++20 mode instead.

NOTE: The resulting libc++ library will not be C++23 compatible! Please
try to avoid shipping it, and use gcc 13 instead, if you must use gcc.

Apply libc++ fix for <ranges> not compiling at all

Merge commit 44cdca37c01a from llvm git (by Arthur O'Dwyer):

[libc++] Define `namespace views` in its own detail header.

Discovered in the comments on D118748: we would like this namespace
to exist anytime Ranges exists, regardless of whether concepts syntax
is supported. Also, we'd like to fully granularize the <ranges> header,
which means not putting any loose declarations at the top level.
