hugetlb: Simplify make_huge_pte()

mk_huge_pte() is a bad API.  Despite its name, it creates a normal
PTE which is later transformed into a huge PTE by arch_make_huge_pte().
So replace the page argument with a folio argument and call folio_mk_pte()
instead.  Then, because we now know this is a regular PTE rather than a
huge one, use pte_mkdirty() instead of huge_pte_mkdirty() (and similar
functions).
