GDK W32: Fix shown window position calculation for dialogs and splashes

Two errors here:
1) A typo in splashscreen rectangle calculation - sets right twice
   instead of setting top
2) Centering for dialogs is off because it doesn't convert
   GDK virtual desktop coordinates to Windows WM virtual desktop
   coordinates by adding _gdk_offset_*
