Make DisplayListRenderer inherit from Canvas, merge JNI

Incrementally unify the upper layers for Skia and HWUI.
Remove redundant code from GLES20Canvas.java; instead
use inherited mNativeCanvasWrapper and superclass method
definitions.

Moves some unrelated SkPaint utility functions from Renderer
to new utils/PaintUtils.
