drm/virtio: Implement VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING cmd
This cmd is useful to let the VMM (i.e, Qemu) know that the backing
store associated with a resource is no longer valid, so that the VMM
can perform any cleanup or unmap operations.
The fence related changes and virtio_gpu_object_detach()/
virtio_gpu_detach_object_fenced() routines are extracted from a
patch by Dmitry Osipenko <dmitry.osipenko@collabora.com>.
