mm/memory: add any_dirty optional pointer to folio_pte_batch()
This commit adds the any_dirty pointer as an optional parameter to
folio_pte_batch() function. By using both the any_young and any_dirty
pointers, madvise_free can make smarter decisions about whether to clear
the PTEs when marking large folios as lazyfree.
