[libc++][PMR] Deprecate the implementation in std::experimental

[philnik]

Summary

This commit deprecates <experimental/memory_resource> since we now ship the non-experimental
version of it. Per the libc++ policy [1], we are deprecating the experimental feature in
upcoming LLVM 16 and will remove it entirely in LLVM 18.

[Mordante]

Thanks for patch! Please update the release notes with this deprecation.

[ldionne]

LGTM but I agree we need to add a release note.

Needs description.

Do not commit without one.

The description should include *why* these were deprecated, (so mention the policy, or the bit of the standard that deprecates them.)

LGTM w/ a suggested rewording of the release note. Thanks for adding a link to the policy in the commit message. Also, the commit message could be reworded to

This should minimize the amount of work that someone has to do in order to understand what's the change and the context around it.
