mm: remove unused inline functions from include/linux/mm_inline.h

Remove the following unused inline functions from mm_inline.h:

1.  All uses of add_page_to_lru_list_tail() have been removed since
   commit 7a3dbfe8a52b ("mm/swap: convert lru_deactivate_file to a
   folio_batch"), and it can be replaced by lruvec_add_folio_tail().

2.  All uses of __clear_page_lru_flags() have been removed since commit
   188e8caee968 ("mm/swap: convert __page_cache_release() to use a
   folio"), and it can be replaced by __folio_clear_lru_flags().

They are useless, so remove them.
