GDK W32: Fix the filling of MINMAXINFO

Browse Source 
1) MSDN says that the coordinates of the maximized window
   must be specified as if the window was on the primary display,
   even if nearest display where it ends up is not the primary display.
   So instead of using nearest display work area verbatim,
   use it only to account for taskbar size, while using
   primary display top-left corner (0:0) as the reference point.
2) MSDN says that max tracking size is a system property, we
   should just call GetSystemMetrics() and use that.
