  -----------
  [libc++] Reduce the dependency of the locale base API on the base system from the headers (#117764)

Many parts of the locale base API are only required when building the
shared/static library, but not from the headers. Document those
functions and carve out a few of those that don't work when
_XOPEN_SOURCE is defined to something old.

Fixes #117630
