Move AnimationTimeline methods related to Styleable to Styleable

[Antoine Quint]

A number of public methods on AnimationTimeline make no use of any AnimationTimeline instance variables and instead call into Styleable:

    void elementWasRemoved(const Styleable&);
    void willChangeRendererForStyleable(const Styleable&);
    void cancelDeclarativeAnimationsForStyleable(const Styleable&);
    void animationWasAddedToStyleable(WebAnimation&, const Styleable&);
    void animationWasRemovedFromStyleable(WebAnimation&, const Styleable&);
    void removeDeclarativeAnimationFromListsForOwningElement(WebAnimation&, const Styleable&);
    void updateCSSAnimationsForStyleable(const Styleable&, const RenderStyle* currentStyle, const RenderStyle& afterChangeStyle, const RenderStyle* parentElementStyle);
    void updateCSSTransitionsForStyleable(const Styleable&, const RenderStyle& currentStyle, const RenderStyle& newStyle);

These should all be on Styleable.

Stylable is a pretty generic name, but all these functions are related to animations. Maybe this should be called something like AnimatableStyleable?

A Styleable is a struct that is an Element/PseudoId pair. It's primarily used for animations, but not only.
