ANDROID: mm: export delete_from_swap_cache for vendor module

For asynchronous swap devices, folio can remain as swapcached even
after swap-out process is completed and will be deleted from
swapcache in next reclaimation trial.

To remove swapcaches right after swap-out is done, export
delete_from_swap_cache() function for vendor module.
