Additionally, better define behavior around null outline providers:
A view with an empty outline, and setClipToOutline=true will not be
rendered, though one with a null outline provider
(and thus no outline) will be.

A View's outline is now managed by its outline provider. This means
the outline is automatically requeried when needed (e.g. drawable
updates or resize), with customizable querying behavior.
Also adds 'isFilled' property to outline, to be used for hinting
shadow overdraw avoidance.
