mm: update generic_get_unmapped_area[_topdown]() to use vma_flags_t

As part of the changes converting VMA flags from a system word size to a
bitmap, extend this change to generic_get_unmapped_area() and
generic_get_unmapped_area_topdown(), which also allows us to convert
stack_guard_placement() as well.

We retain arch_get_unmapped_area() and arch_get_unmapped_area_topdown()
as-is for now, using legacy_to_vma_flags() as necessary to do so.

No functional change intended.
