mm/filemap: Add NUMA mempolicy support to filemap_alloc_folio()
Add a mempolicy parameter to filemap_alloc_folio() to enable NUMA-aware
page cache allocations. This will be used by upcoming changes to
support NUMA policies in guest-memfd, where guest_memory need to be
allocated NUMA policy specified by VMM.
All existing users pass NULL maintaining current behavior.
