Add a capability to let userspace discover whether guest_memfd supports

itself being supported, but also on whether KVM can manipulate the
direct map at page granularity at all (possible most of the time, just
arm64 is a notable outlier where its impossible if the direct map has
been setup using hugepages, as arm64 cannot break these apart due to
break-before-make semantics).

Not sure how KVM folks handle that, but I suspect we would just want to
squash that into the previous commit,
