contrib/vhost-user-gpu: implement get_edid feature
Implement the virtio-gpu feature in contrib/vhost-user-gpu, which was unsupported until now. In this implementation, the feature is enabled inconditionally to avoid creating another optional config argument. Similarly to get_display_info, vhost-user-gpu sends a message back to the frontend to have access to all the display information. In the case of get_edid, it also needs to pass which scanout we should retrieve the edid for. The VHOST_USER_GPU_PROTOCOL_F_EDID protocol feature is required if the frontend sets the VIRTIO_GPU_F_EDID virtio-gpu feature. If the frontend sets the virtio-gpu feature but does not support the protocol feature, the backend will abort with an error.
