Deprecate physics-android and use DynamicAnimation in supportlib

SpringAnimation requires the caller to pass in the View target and ViewProperty property ahead of time. The API looks like this:

SpringAnimation spring = new SpringAnimation(viewTarget, DynamicAnimation.X);
spring.start();

The SpringAnimation is responsible for writing to the target's property on every time step.

This is not compatible with Android's current data pipeline setup, where the writing's responsibility lies with the runtime:

MotionObservable stream = source().operator().operator();
runtime.write(stream, target, property);

However, it is similar to the coreAnimation channel introduced in material-motion-swift.
