[Web Animations] Add a new CSSAnimation subclass of WebAnimation

[Antoine Quint]

As we implement CSS Animations over the Web Animations engine, we’ll need a way to represent an animation created using CSS Animations. To do so, we’ll add a new CSSAnimation subclass of WebAnimation. This Radar covers the basic task of adding the new class to WebCore.

why not just return adoptRef(*new CSSAnimation(target.document());

You have no way to set the animation name yet.

Indeed, this is just setting the stage for future patches where we'll be adding more code to CSSAnimation::create().
