Handle view properties at the native level

Basic functionality of handling View properties (transforms,
left/right/top/bottom, and alpha) at the native DisplayList level.
This logic is disabled for now (via compile-time flags in View.java and
DisplayListRenderer.h) as we continue work on it (there is no advantage
to the new approach until we optimize invalidation and rendering paths
to use the new code path).
