isabellekim 5bf8f92e78 Update RippleDrawableCompat to use MaterialShapeDrawable as a delegate and implement ConstantState.
This will make RippleDrawable work with a single-value ColorStateList as previously it getConstantState().newDrawable() would recreate a MaterialShapeDrawable, losing the logic in RippleDrawableCompat.
