Update the nine patch layer to use UI resources

The old nine-patch layer used priority resource manager for requesting textures.
This patch updates the nine-patch layer to use the UI resource manager. 
this patch clarifies the semantics of the aperture in both image and layer
The new semantics corresponds to existing logic on the android-side.

Changes have been made to UIResourceBitmap to use SkPixelRef as ref-counted
of the bitmap content.

The android-side changes:
