[PATCH v3] drm/virtio: add new virtio gpu capset definitions

[Huang Rui <ray.huang@amd.com>]

These definitions are used fro qemu, and qemu imports this marco in the
headers to enable gfxstream, venus, cross domain, and drm (native
context) for virtio gpu. So it should add them even kernel doesn't use
this.
