Suppress pointer event stream when a drag starts

According to the HTML spec, when a drag starts the user agent should
send the appropriate events to the drag source to indicate that the
pointer event stream has been ended and that it shouldn't expect any
more events from this pointer. The events to be sent are "pointerout",
"pointercancel" and "pointerleave".

This code had been partially implemented for mouse events, and this CL
corrects the implementation and expands it to gesture based drags as
well.
