mm: remove folio_prep_large_rmappable()

Now that prep_compound_page() initialises folio->_deferred_list,
folio_prep_large_rmappable()'s only purpose is to set the large_rmappable
flag, so inline it into the two callers.  Take the opportunity to convert
the large_rmappable definition from PAGEFLAG to FOLIO_FLAG and remove the
existance of PageTestLargeRmappable and friends.
