Fix routing of OSR input events inside iframes (fixes issue #2789) 

Mouse events need to be routed to the correct view and
CefRenderWidgetHostViewOSR::TransformPointToCoordSpaceForView needs to be
properly implemented for
RenderWidgetHostInputEventRouter::DispatchTouchscreenGestureEvent to
transform event position in the target widget.
