mm: migrate: add isolate_folio_to_list()
Add isolate_folio_to_list() helper to try to isolate HugeTLB, no-LRU
movable and LRU folios to a list, which will be reused by
do_migrate_range() from memory hotplug soon, also drop the
mf_isolate_folio() since we could directly use new helper in the
soft_offline_in_use_page().
