drm/probe-helper: Introduce .force_ctx() connector callback
The .force() connector callback is invoked by drm_helper_probe_single_connector_modes() while the modeset acquire context it created is live, but the hook signature provides no way to pass it down, e.g. to support implementations needing to lock further objects. Add a .force_ctx() variant to drm_connector_helper_funcs, taking the acquire context and returning an error code, so that -EDEADLK propagates into the existing retry path. When provided, it takes precedence over drm_connector_funcs' .force(), which is kept for existing users. This is a prerequisite for SCDC status synchronization in the HDMI connector framework.
