Build layer immediately when setting it in ViewPropertyAnimator

Previously, withLayer() would simply set the layer type in the runnable
called in onAnimationStart(). Now we also call buildLayer(), to get it
out of the way prior to the view drawing for the first time after the
animation begins.

Issue #9422420 ViewPropertyAnimator.withLayer() should build layer immediately
