mmzone: introduce folio_is_zone_movable()

Patch series "Replace is_longterm_pinnable_page()", v2.

This patchset introduces some more helper functions for the folio
conversions, and converts all callers of is_longterm_pinnable_page() to
use folios.


This patch (of 5):

Introduce folio_is_zone_movable() to act as a folio equivalent for
is_zone_movable_page().  This is to assist in later folio conversions.
