Runtime-enabling <track> involves enabling/disabling entire interfaces/classes (e.g. HTMLTrackElement, TextTrack, TextTrackCue, etc.) not just individual class attributes. Therefore, this change will modify the CodeGenerator to accept the EnabledAtRuntime idl attribute for interfaces.

Comment on attachment 109651 [details] Patch Looks great.
Don't we test runtime features using layoutTestController additions? We certainly can test some preferences that way, but I'm not sure if there is precedent for testing v8 runtime features that way.
Presumably we'll get that test coverage when we test <track> itself.
