mm: introduce page_lru_base_type()
Instead of abusing page_is_file_cache() for LRU list index arithmetic, add
another helper with a more appropriate name and convert the non-boolean
users of page_is_file_cache() accordingly.
This new helper gives the LRU base type a page is supposed to live on,
inactive anon or inactive file.
