[WINESYNC][COMCTL32] Listview: Initialize marqueeRect from left-click coordinates before starting a marquee highlight (reactos#5555)

The infoPtr->marqueeRect structure is not currently initialized before the
marquee highlight sequence starts, resulting in the RECT having initial
coordinates of (0,0)-(0,0). These coordinates cause the first item in
the listview control to be identified as being within the range of the
marqueeRect's coordinates.

That item is then set to LVIS_SELECTED even though it is not part of the
marquee selection.
