fix(force invert): fix white-on-white text when text is drawn against a fill rect in the same RenderNode

This fixes issues with custom Views that draw background and text in the
same View/RenderNode. Instead of trying to force the individual paints
to be dark, we simply invert the whole view.

Adds a new hasFill() member to DisplayList and Canvas so that we record
when the RenderNode has a call that fills the background.

Also adds a new Container usage hint type, for this exact situation.
