Jianyue Wu 0ba14428ab mm: rename swap.c to folio.c
Rename mm/swap.c to mm/folio.c so the filename better matches the code's
main responsibility.

This keeps the implementation split from swap-specific code without
changing the published LRU helper interfaces.

Update MAINTAINERS and the remaining mm/swap.c documentation references
after the rename.
