mm: add FGP_UNCACHED 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.
