Currently in RenderWidgetHostInputEventRouter, we use
TransformPointToCoordSpaceForView [1] to transform locations, which uses
SurfaceHittest in normal chrome. We don't want to use SurfaceHittest in
normal chrome and can't use SurfaceHittest in OOP-D.

This CL changes to use HitTestQuery::TransformLocationForTarget instead.
