  Log Message:
  -----------
  [libc++] [ranges] Permit std::mergeable and std::sortable with HAS_NO_INCOMPLETE_RANGES.

This follows the general direction of D118736 that
`_LIBCPP_HAS_NO_INCOMPLETE_RANGES` does *not* guard anything outside
of the `std::ranges::` namespace itself. This means we must permit
`ranges::less` etc. in no-ranges mode; that seems fine to me.
