ANDROID: mm/readahead: add for bypass high order allocation
EROFS supports large folios on kernel-6.12 which enable high order
allocation with direct_reclaim flags. This might increase the latency
on UX task with filemap_fault(). Add a vendor hook here to bypass
unnecessary allocation in certain scenarios.
