mm: prepare to remove /proc/sys/vm/hugepages_treat_as_movable

Now hugepage migration is enabled, although restricted on pmd-based
hugepages for now (due to lack of testing.) So we should allocate
migratable hugepages from ZONE_MOVABLE if possible.

This patch makes GFP flags in hugepage allocation dependent on migration
support, not only the value of hugepages_treat_as_movable.  It provides no
change on the behavior for architectures which do not support hugepage
migration,
