mm/hugetlb: convert hugetlb fault paths to use alloc_hugetlb_folio()

Change alloc_huge_page() to alloc_hugetlb_folio() by changing all callers
to handle the now folio return type of the function.  In this conversion,
alloc_huge_page_vma() is also changed to alloc_hugetlb_folio_vma() and
hugepage_add_new_anon_rmap() is changed to take in a folio directly.  Many
additions of '&folio->page' are cleaned up in subsequent patches.

hugetlbfs_fallocate() is also refactored to use the RCU +
page_cache_next_miss() API.
