[bfcache] Stop ServiceScriptedAnimations when frozen

In the wild, we saw a case where JavaScript gets executed because of
ServiceScriptedAnimations while a page is in bfcache.
This seems to be a case where a user navigates to a page and then goes
back immediately. BeginMainFrame() initiates this JS execution.

The problems is that ServiceScriptedAnimations did not consider frozen state/ bfcache.

This CL replaces IsContextPaused() with IsContextFrozemOrPaused() in
ServiceScriptedAnimations.
