ClutterLayerNode currently skips pushing and popping its framebuffer to the paint context when no rectangles are added to it. However, it's still useful to do that, since we might want to render child nodes to the offscreen and reuse the pipeline in a later node. Make ClutterLayerNode push and pop its framebuffer even without rectangles. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1340
