Remove CompositingUpdateOnScroll

Remove CompositingUpdateOnScroll

This CL teaches the callers of CompositingUpdateOnScroll how to do partial
compositing updates. Now that they're smarter, we can use
CompositingUpdateAfterCompositingInputChange and we don't need
CompositingUpdateOnScroll anymore.

lgtm, but can we not make setNeedsToUpdateAncestorDependentProperties() call
setNeedsCompositingUpdate(CompositingUpdateAfterCompositingInputChange) ?

It's really weird that it doesn't, like setNeedsStyleRecalc() calls
scheduleVisualUpdate().

Sure.  If you don't mind, I'll do that in a separate CL.
