mm: remove PageWriteback
The last caller of PageWriteback() was removed in commit f75987e543c2
("libceph: remove pinning assertion in ceph_msg_data_iter_next()"). This
flag is now only used on folios, so we can remove all the page accessors.
folio_test_clear_writeback() is not used, so don't add
FOLIO_TEST_CLEAR_FLAG() for it.
