[libc++] Make the __availability header a sub-header of __config (#93083)
In essence, this header has always been related to configuration of
the library but we didn't want to put it inside <__config> due to
complexity reasons. Now that we have sub-headers in <__config>, we
can move <__availability> to it and stop including it everywhere since
we already obtain the required macros via <__config>.

67b37af4cd [libc++][Modules] Add missing __fwd includes
A few __fwd includes are missing from public modules that will become noticeable when the private submodules are split into their own top level modules (D144322). Add the missing includes.

2da049a141 [libc++] Add incomplete availability markup for std::pmr
This fixes rdar://110330781, which asked for the feature-test macro
for std::pmr to take into account the deployment target. It doesn't
fix https://llvm.org/PR62212, though, because the availability markup
itself must be disabled until some Clang bugs have been fixed.

This is pretty vexing, however at least everything should work once
those Clang bugs have been fixed. In the meantime, this patch at least
adds the required markup (as disabled) and ensures that the feature-test
macro for std::pmr is aware of the deployment target requirement.

f1ea0b11ca [libc++] Merge _LIBCPP_FUNC_VIS, _LIBCPP_TYPE_VIS and _LIBCPP_EXCEPTION_ABI into _LIBCPP_EXPORTED_FROM_ABI
These macros are always defined identically, so we can simplify the code a bit by merging them.

4f15267d3d [libc++][NFC] Replace _LIBCPP_STD_VER > x with _LIBCPP_STD_VER >= x
This change is almost fully mechanical. The only interesting change is in `generate_feature_test_macro_components.py` to generate `_LIBCPP_STD_VER >=` instead. To avoid churn in the git-blame this commit should be added to the `.git-blame-ignore-revs` once committed.

243da90ea5 [libc++] Add the C++17 <memory_resource> header (mono-patch)
This patch is the rebase and squash of three earlier patches.
It supersedes all three of them.

- D47111: experimental monotonic_buffer_resource.
- D47358: experimental pool resources.
- D47360: Copy std::experimental::pmr to std::pmr.

The significant difference between this patch and the-sum-of-those-three
is that this patch does not add `std::experimental::pmr::monotonic_buffer_resource`
and so on. This patch simply adds the C++17 standard facilities, and
leaves the `std::experimental` namespace entirely alone.
