mm, swap: split swap cache preparation loop into a standalone helper
To prepare for the removal of swap cache bypass swapin, introduce a new
helper that accepts an allocated and charged fresh folio, prepares the
folio, the swap map, and then adds the folio to the swap cache.
This doesn't change how swap cache works yet, we are still depending on
the SWAP_HAS_CACHE in the swap map for synchronization. But all
synchronization hacks are now all in this single helper.
No feature change.
