mm/rmap: introduce folio_add_anon_rmap_[pte|ptes|pmd]()
Let's mimic what we did with folio_add_file_rmap_*() so we can similarly
replace page_add_anon_rmap() next.
Make the compiler always special-case on the granularity by using
__always_inline.
For the PageAnonExclusive sanity checks, when adding a PMD mapping, we're
now also checking each individual subpage covered by that PMD, instead of
only the head page.
Note that the new functions ignore the RMAP_COMPOUND flag, which we will
remove as soon as page_add_anon_rmap() is gone.
