https://bugs.webkit.org/show_bug.cgi?id=112104

Patch by Tien-Ren Chen <trchen@chromium.org> on 2013-03-12
Reviewed by James Robinson.

Need to notify ScrollingCoordinatorChromium whenever m_layerForHorizontalScrollbar /
m_layerForVerticalScrollbar changes, for correct lifetime management.

No new tests. Difficult to test lifetime management internal to ScrollingCoordinatorChromium.
