Revert of Move some scroll invalidations to the paint invalidation phase

Revert of Move some scroll invalidations to the paint invalidation phase (patchset #4 id:60001 of https://codereview.chromium.org/498773007/)

Reason for revert:
The patch is likely the culprit for Mac IMAGE failures.
Example: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=@ToT%20Blink&tests=compositing%2Freflections%2Fsimple-composited-reflections.html&testType=layout-tests&showChrome=true

Original issue's description:
> Move some scroll invalidations to the paint invalidation phase
> 
> Scrolling used to generate immediate invalidations that are now
> postponed to the paint invalidation phase. In order to make this
> works, scrolling updates needs to to happen before paint
> invalidations.
> 
> The test changes are either neutral (same amount of invalidations,
> except that we generate them one at a time) or
> compositing/repaint/fixed-pos-inside-composited-intermediate-layer
> is a progression.
> 
> Committed: https://src.chromium.org/viewvc/blink?view=rev&revision=181475
