Reviewed by Simon Fraser.

Before this patch, CSSTransition::create() would expect a `const RenderStyle*` for the oldStyle parameter,
but it makes no sense since a transition necessarily operates on an existing underlying style. So now we
make that parameter a `const RenderStyle&`.

We can also make a similar change to KeyframeEffect::computeCSSTransitionBlendingKeyframes().
