Revert 222839 "Make inverse transform animations easier to creat..."

Causes LayerAnimatorTest.TestScopedCounterAnimation to fail.

> Make inverse transform animations easier to create, using ScopedLayerAnimationSettings.
> 
> https://codereview.chromium.org/22861008/ Introduces inverse animations which allow layers to counter-animate against a base layer. However, manually building the animation elements is repetitive and error prone, this change makes these animations simpler to write.
> 
> Users should use it in this manner:
> 
> // Input values
> Layer *base, *inversed1, *inversed2;
> gfx::Transform new_transform;
> 
> void foo() {
>   ui::ScopedLayerAnimationSettings settings(base->GetAnimator());
>   settings.SetInverselyAnimatedBaseLayer(base);
>   settings.AddInverselyAnimatedLayer(inversed1);
>   settings.AddInverselyAnimatedLayer(inversed2);
> 
>   base->SetTransform(new_transform);
> }
