[libc++] Remove obsolete header restrictions for _LIBCPP_HAS_NO_THREADS (#107437)

Browse Source 
The _LIBCPP_HAS_NO_THREADS carve-out does not result in hard errors
anymore, but the patch that changed that forgot to update the header
restrictions we use to auto-generate several files.

We can also remove the restrictions for the no-localization build and
no-wide-characters, but doing it is less straightforward so I'm leaving
it out of this patch.
