hw/xwin: Link directly to TrackMouseEvent()

Browse Source 
TrackMouseEvent has existed in user32 since at least NT4, so
don't bother with jumping through all the ancient compatibility hoops
of finding if _TrackMouseEvent() exists in comctl32 so it can check
if TrackMouseEvent() exists in user32 to see if it needs to emulate
it...
