Vivek Kasireddy 53ba78de06 mm/gup: introduce check_and_migrate_movable_folios() 
This helper is the folio equivalent of check_and_migrate_movable_pages(). 
Therefore, all the rules that apply to check_and_migrate_movable_pages()
also apply to this one as well.  Currently, this helper is only used by
memfd_pin_folios().

This patch also includes changes to rename and convert the internal
functions collect_longterm_unpinnable_pages() and
migrate_longterm_unpinnable_pages() to work on folios.  As a result,
check_and_migrate_movable_pages() is now a wrapper around
check_and_migrate_movable_folios().
