clutter/stage-view: Add API to get view color state

Browse Source 
This aims to provide the color state used for compositing for a specific
view. It's currently hard coded to default, but will eventually be
configured depending on the monitor and configuration. It's intended to
be used as a target color state for rendering with color awareness.
