Adding support for sending horizonatal mouse wheel information in Chrome ASH on Windows 8.

Currently using the horizontal mouse wheel also causes vertical scrolling. With this change we send over
a flag in the mouse messages which indicates if horizontal scrolling is being done and if yes we create
the right MouseWheelEvent instance.
