OvmfPkg: VIRTIO_DEVICE_PROTOCOL: pass VRING object to SetQueueAddress()

In virtio-1.0, it is not enough to pass the base address of the virtio
queue to the hypervisor (as a frame number); instead it will want the
addresses of the descriptor table, the available ring, and the used ring
separately. Pass the VRING object to the SetQueueAddress() member
function; this will enable a virtio-1.0 implementation. Convert the
current producers and consumers to this prototype.
