[libc++] Re-implement LWG2770 again * 2 (#132598)

1013fe3c0cfd7582e94ef2d4bfd79da7ea1a1289 used to implement LWG2770, but
cb0d4df97490ec2d2b1cdf7574d26b1bc4063599 made LWG2770 unimplemented
again because of CWG2386.

This patch re-implements LWG2770, while keeping the libc++-specific
implementation strategy (which is controversial as noted in LWG4040).

Drive-by:
- Make the test coverage for the controversial part noted in LWG4040
libc++-only.
- Add the previously missed entry for LWG2770 to the documentation.
