This change does NOT support large folios. This shouldn't be an issue as

This is the equivalent of find_get_pages_range_tag(), except for folios

One noteable difference is filemap_get_folios_tag() does not take in a
maximum pages argument. It instead tries to fill a folio batch and stops
either once full (15 folios) or reaching the end of the search
