When styling with the Servo backend, we should also use the Servo backend to determine if a property is animatable or not. However, if we do this, Servo_Property_IsAnimatable will start returning true for the 'display' property once we mark that as animatable in Servo (for SMIL). Even if we later fail to actually animate 'display' (due checks added to Servo in the next patch) we still need to treat 'display' as un-animatable in KeyframeUtils so that we don't *read* the 'display' property of Keyframe objects passed to the Animations API, since that is observable. This patch makes us consult Servo_Property_IsAnimatable when using the Servo backend and also explicitly treat the 'display' property as not animatable.
