This reverts commit 3df38ad3.

Reason for revert: OverflowScrollInterruptedByInstantScroll fails on linux-chromeos-dbg

BUG=1133037

Original change's description:
> Rewrite scroll interruption tests into browser tests
>
> After we finish the scroll unification, the scrolls happens mainly on
> the compositor thread, and the scroll code in the main thread will be
> removed. eventSender sends the scroll events to main thread, so it
> would not work after the scroll unification. We rewrite below tests
> fast/scroll-behavior/main-frame-interrupted-scroll.html,
> fast/scroll-behavior/overflow-interrupted-scroll.html and
> fast/scroll-behavior/subframe-interrupted-scroll.html into browser tests
> because we cannot guarantee that the scroll arrives before the animation
> completes.
