mm/huge_memory: move folio split common code to __folio_split()
This is a preparation patch for folio_split(). In the upcoming patch folio_split() will share folio unmapping and remapping code with split_huge_page_to_list_to_order(), so move the code to a common function __folio_split() first. Add a TODO for splitting large shmem folio in swap cache.
