We no longer set the widget on construction, but instead require an explicit call to gtk_widget_add_controller(). This way, the reference handling becomes explicit and bindable. Because gtk_widget_add_controller() is (transfer: full), we don't even need to unref the controller after adding it. And we don't need to keep track of it, because controllers get cleaned up by GtkWidget.
