[WIN32SS][GDI] Assume pso->sizlBitmap.cy positiveness (#1743)

Browse source 
We assume pso->sizlBitmap.cy is positive. CORE-15995

Because pso->sizlBitmap.cy is certificated as a positive value after initialization in SURFACE_AllocSurface, so we can safely omit abs and labs (absolute) function calls for it.
