KVM: arm/arm64: GICv4: Add property field and per-VM predicate
Add a new has_gicv4 field in the global VGIC state that indicates whether the HW is GICv4 capable, as a per-VM predicate indicating if there is a possibility for a VM to support direct injection (the above being true and the VM having an ITS).
