For an external display, via Spice currently, there is a callback to block/unblock the rendering in the same thread. But with the vhost-user-gpu backend, the qemu process doesn't handle the rendering itself, and the blocking callback isn't effective. Instead, the backend must be notified when the display code is done. Fix this by adding a new GraphicHwOps callback to indicate the GL state is flushed, and we are done manipulating the shared GL resources. Call it from gtk and spice display.
