[libc++] Add incomplete availability markup for std::pmr

[ldionne]

Summary

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.

I *think* it does the correct thing, but you should be adding tests to verify that. See for example libcxx/test/libcxx/thread/atomic.availability.verify.cpp.

This function probably needs to be marked too since it calls release.

I usually use the attribute on the entire class/struct.

Thanks for the info! I didn't know you could mark a class as unavailable.

[ldionne]

I think you need to propagate availability macros to the typedefs in std::pmr. You should also add a simple test for those -- it's probably fine to put everything inside the same file.

Missing a comment like all the other ones.

LGTM once CI is passing. I'll try to get you access to our CI node per our discussion.

[ldionne]

Rebase onto main. There's a lot of problems that I think are basically Clang bugs with the availability attributes.

Update commit message

[Mordante]

LGTM modulo one comment.

libcxx/test/libcxx/utilities/utility/mem.res/pmr.availability.verify.cpp

Based on the other test we haven't backported PMR.

[ldionne]

Rebase and trigger CI

[ldionne]

Disable availability markup and explain why.

[ldionne]

Poke CI

[ldionne]

Rebase on top of GCC fix for CI.
