scene_graph: Introduce sway_scene_descriptor

Browse source 
Across a wayland compositor, there are multiple shells: It can be
a toplevel, or a layer_shell, or even something more meta like a drag
icon or highlight indicators when dragging windows around.

This object lets us store values that represent these modes of operation
and keep track of what object is being represented.
