VectorDrawable native rendering - Step 2 of MANY

Introduced PathData in Java, which is effectively a thin layer around the
native instance. PathData holds the verbs and points which is being used
in path morphing/interpolation. The verbs and points can be interpreted
into skia path commands, which is now done in native and therefore saves
a handful of JNI calls during path creation.

Removed the old PathDataNode mechanism and changed the PathEvaluator
to use PathData instead.

Also added tests and a microbench. Also ran CTS tests for VectorDrawable
and AnimatedVectorDrawable, and passed all of the existing tests.
