hugetlb: batch TLB flushes when restoring vmemmap

Update the internal hugetlb restore vmemmap code path such that TLB
flushing can be batched.  Use the existing mechanism of passing the
VMEMMAP_REMAP_NO_TLB_FLUSH flag to indicate flushing should not be
performed for individual pages.  The routine
hugetlb_vmemmap_restore_folios is the only user of this new mechanism, and
it will perform a global flush after all vmemmap is restored.
