Plumb drag event info through from the renderer. This CL appends the following
two pieces of information to the StartDragging IPC:
1. Whether the drag was started by a touch event or mouse event
2. The location of drag start. This information is needed for chromeos and was
currently being read from the platform. But that is not possible (also not
correct) for touch based drag/drop. So we pass this information from the
renderer.
