We currently create an OpenGL context when opening the DRM fd if 3D is available.
We may need other context types (VK,..) in the future, and the plan is to have explicit initialization for that.
For explicit initialization to work, we need to factor out virtio_gpu_create_context from driver initialization.

For old userspace, initialization will still be implicit.
For backwards compatibility, enqueue virtio_gpu_cmd_context_create after the first 3D ioctl.
