Relay mouse event synthesization information
Make platform plugins, like the windows one, able to indicate
if a mouse event is synthesized from a touch event by the OS.
This will be valuable information for the Quick2 event handlers.
No new member variables are added to QMouseEvent. Instead, the enum
value is encoded in the caps member, there are plenty of bits
available in it.
This introduces Qt::MouseEventSource and QMouseEvent::source() as
public APIs.
