KVM: arm64: nv: Allow userspace to request KVM_ARM_VCPU_NESTED_VIRT

Since we're (almost) feature complete, let's allow userspace to
request KVM_ARM_VCPU_NESTED_VIRT by bumping the KVM_VCPU_MAX_FEATURES
up. We also now advertise the feature to userspace with a new capability.

It's going to be great...
