mm/swap: Add folio_mark_accessed()
Convert mark_page_accessed() to folio_mark_accessed(). It already
operated on the entire compound page, but now we can avoid calling
compound_head quite so many times. Shrinks the function from 424 bytes
to 295 bytes (shrinking by 129 bytes). The compatibility wrapper is 30
bytes, plus the 8 bytes for the exported symbol means the kernel shrinks
by 91 bytes.
