mm/rmap: convert page_dup_file_rmap() to folio_dup_file_rmap_[pte|ptes|pmd]()

Let's convert page_dup_file_rmap() like the other rmap functions.  As
there is only a single caller, convert that single caller right away and
remove page_dup_file_rmap().

Add folio_dup_file_rmap_ptes() right away, we want to perform rmap baching
during fork() soon.
