Peter Xu 229f3fa778 mm/hugetlb: introduce huge pte version of uffd-wp helpers
They will be used in the follow up patches to either check/set/clear
uffd-wp bit of a huge pte.

So far it reuses all the small pte helpers.  Archs can overwrite these
versions when necessary (with __HAVE_ARCH_HUGE_PTE_UFFD_WP* macros) in the
future.
