backend/drm: extract connect_drm_connector() logic
We already have disconnect_drm_connector() to handle the CONNECTED → DISCONNECTED transition. Let's add connect_drm_connector() to handle DISCONNECTED → CONNECTED. This makes scan_drm_connectors() shorter and easier to follow. No functional change, literally just moving code around.
