Callers that want the folio behind a present PTE spell it out as
page_folio(pte_page(pte)).

Add pte_folio() as the folio companion to pte_page(), and convert the
callers in fs/proc/task_mmu.c and mm/hugetlb.c.

Preparation for the anonymous collapse engine, which reads the folio
behind a PTE in several places.

Oh nice, this could clean up some things in the
get_user_pages code too, when we get around to
tech debt there.

This could probably go in by itself.
