ClutterLayerNode is the "offscreen framebuffer" node, that paints it's child nodes in a separate framebuffer, and then copies that framebuffer to the parent one. It'll be useful to hand ClutterLayerNode which framebuffer and pipeline to use, as this is a requirement for porting e.g. ClutterOffscreenEffect and subclasses. Add a new clutter_layer_node_new_to_framebuffer() API. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1340>
