Extend __filemap_get_folio() to support NUMA memory policies by renaming the implementation to __filemap_get_folio_mpol() and adding a mempolicy parameter. The original function becomes a static inline wrapper that passes NULL for the mempolicy. This infrastructure will enable future support for NUMA-aware page cache allocations in guest_memfd memory backend KVM guests.
