drm/virtio: implement context init: track {ring_idx, emit_fence_info} in virtio_gpu_fence
Each fence should be associated with a [fence ID, fence_context,
seqno]. The seqno number is just the fence id.
To get the fence context, we add the ring_idx to the 3D context's
base_fence_ctx. The ring_idx is between 0 and 31, inclusive.
Each 3D context will have it's own base_fence_ctx. The ring_idx will
be emitted to host userspace, when emit_fence_info is true.
