arm64: mm: support batch clearing of the young flag for large folios

Currently, contpte_ptep_test_and_clear_young() and
contpte_ptep_clear_flush_young() only clear the young flag and flush TLBs
for PTEs within the contiguous range.  To support batch PTE operations for
other sized large folios in the following patches, adding a new parameter
to specify the number of PTEs that map consecutive pages of the same large
folio in a single VMA and a single page table.

While we are at it, rename the functions to maintain consistency with
other contpte_*() functions.
