Enable DisplayList properties

Browse Source 
This CL simply enables DisplayList property functionality. The code for
this feature is already there, but it's been disabled by default pending further
testing and analysis. This change sets these build-type flags to true
so that all hw-accelerated apps will now use DisplayList properties by default.

In particular, this feature enables a fast-path for changes that affect the
handful of View properties involved in animations (alpha, translationX, etc.).
Setting these properties now gets propagated to the native DisplayList associated
with the View, avoiding costly recreation of the SDK-level DisplayList and
also enabling faster invalidation of the view hierarchy.
