Christoffer Dall 89b0e7de34 KVM: arm64: nv: Introduce nested virtualization VCPU feature 
Introduce the feature bit and a primitive that checks if the feature is
set behind a static key check based on the cpus_have_const_cap check.

Checking vcpu_has_nv() on systems without nested virt enabled
should have negligible overhead.

We don't yet allow userspace to actually set this feature.
