mm: add FGP_DONTCACHE folio creation flag
Callers can pass this in for uncached folio creation, in which case if a
folio is newly created it gets marked as uncached. If a folio exists for
this index and lookup succeeds, then it will not get marked as uncached.
If an !uncached lookup finds a cached folio, clear the flag. For that
case, there are competeting uncached and cached users of the folio, and it
should not get pruned.
