git_commit commit 4a509f853fa4821ecdb0f6bc3b90ddd48794cc8c
Author: A. Jiang <de34@live.cn>

[libc++] Implement comparison operators for `tuple` added in C++23 (#148799)

And constrain the new `operator==` since C++26.

This patch implements parts of P2165R4, P2944R3, and a possibly improved
resolution of LWG3882. Currently, libstdc++ and MSVC STL constrain the
new overloads in the same way.

Also set feature-test macro `__cpp_lib_constrained_equality` and add
related release note, as P2944R3 will completed with this patch.
