Implement the required MMIO accessors for GICv2 and GICv3 for the IGROUPR distributor and redistributor registers. This can allow guests to change behavior compared to running on previous versions of KVM, but only to align with the architecture and hardware implementations. This also allows userspace to configure the interrupts groups for GICv3. We don't allow userspace to write the groups on GICv2 just yet, because that would result in GICv2 guests not receiving interrupts after migrating from an older kernel that exposes GICv2 interrupts as group 1.
