0025142: Visualization breaks triangulation on shared solids in composite solid model

Browse Source 
Test case for 0025142: Visualization breaks triangulation on shared solids in composite solid model

Do not clean the triangulation in StdPrs_ShadedShape::Tessellate() and
let the triangulation tool process the sub-shapes properly.
Treat triangulation consistently in all AIS classes (AIS_Shape, AIS_TexturedShape).
