Revert "Reland "Composite ScrollTimeline scrollSource when appropriate."" 

This reverts commit 48f503a8.

Reason for revert: Failing the Linux Trusty Leak bot

Original change's description:
> Reland "Composite ScrollTimeline scrollSource when appropriate."
> 
> This is a reland of ddd9f0ee

> > This CL makes being the scrollSource of an active (i.e. the scrollSource is
> > scrollable) and attached (i.e. it is being used by at least one WorkletAnimation
> > as a timeline) ScrollTimeline a compositing reason. It does not change the
> > requirement that the scrollSource must be composited for the WorkletAnimation to
> > be sent to the compositor, nor does it change the case where a scrollSource stops
> > being composited whilst a WorkletAnimation is running. Those will be addressed in
> > follow-up CLs.
