#11075: Get rid of the hideous and slow stretch200To240 for SDL backends

 SurfaceSdlGraphicsManager is already scaling whenever the various stretch
 and fit modes are used. I think on most if not all platforms that use it,
 this employs hardware scaling via SDL.

 So if hardware scaling works fine, with the user selected filtering etc.,
 then why is there still this kludge called "stretch200To240", an ugly and
 slow software scaler that is used to do aspect ratio correction in
 SurfaceSDLGraphicsManager, see here:
 https://github.com/scummvm/scummvm/blob/0fd412ca16a1458540cf0f1f0271a29a0e002432/backends/graphics/surfacesdl
 /surfacesdl-graphics.cpp#L1326

 This should be implemented by simply adjusting _activeArea to have the
 correct aspect ratio.
