svx: make SdrGrafObj::mpReplacementGraphic swappable

These GraphicObjects clog up the GraphicManager cache so it's
effectively useless.

Round-tripping the ML bugdoc, this doesn't provide much of a
speed-up by itself, but together with the previous fix it goes from
3:00 to 1:30 (in an optimized build).
