mm/shmem: add shmem_alloc_folio() 

Bugzilla: https://bugzilla.redhat.com/2160210

commit 0c023ef52d769ea064df2c86bcdf29cbedb0a9b7
Author: Matthew Wilcox (Oracle) <willy@infradead.org>
Date:   Thu May 12 20:23:04 2022 -0700

    mm/shmem: add shmem_alloc_folio()

    Call vma_alloc_folio() directly instead of alloc_page_vma().  Add a
    shmem_alloc_page() wrapper to avoid changing the callers.
