vulkan-cereal: add virtio-gpu style versioning
Use the capabilities provided by virtio-gpu to report protocol
version, ring buffer size and buffer size.
In the future, we may ditch the renderControl versioning interface
entirely since caps are cached by the guest and should be a bit
more performant.
