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.
