Add ClutterContent

ClutterContent is an interface for creating delegate objects that handle
what an actor is going to paint.

Since they are a newly added type, they only hook into the new PaintNode
based API.

The position and size of the content is controlled in part by the
content's own preferred size, and by the ClutterContentGravity
enumeration.
