mm: add vma_alloc_zeroed_movable_folio()
Replace alloc_zeroed_user_highpage_movable(). The main difference is
returning a folio containing a single page instead of returning the page,
but take the opportunity to rename the function to match other allocation
functions a little better and rewrite the documentation to place more
emphasis on the zeroing rather than the highmem aspect.
