cc::WorkletAnimation has both scroll_timeline_ and animation_timeline_.
When a worklet animation updates its ScrollTimeline, it is the
scroll_timeline_ that should be updated. However, the other timeline
gets updated due to function inheritance. This will be fixed after
crbug.com/1023508. Until then we should apply a temporary fix.

This patch allows WorkletAnimation to override the base function to
update the scroll_timeline_ correctly.
