mm/rmap: introduce folio_remove_rmap_[pte|ptes|pmd]()
Let's mimic what we did with folio_add_file_rmap_*() and
folio_add_anon_rmap_*() so we can similarly replace page_remove_rmap()
next.
Make the compiler always special-case on the granularity by using
__always_inline.
We're adding folio_remove_rmap_ptes() handling right away, as we want to
use that soon for batching rmap operations when unmapping PTE-mapped large
folios.
