[PATCH v6 15/30] mm: remove arch vma_alloc_zeroed_movable_folio overrides

Now that the generic vma_alloc_zeroed_movable_folio() uses
__GFP_ZERO, the arch-specific macros on alpha, m68k, s390, and
x86 that did the same thing are redundant.  Remove them.

arm64 is not affected: it has a real function override that
handles MTE tag zeroing, not just __GFP_ZERO.
