0027835: Application Framework, BinXCAF - handle correctly faces with NULL surface within BinTools_ShapeSet

Browse Source 
BinTools_ShapeSet::AddGeometry() now writes NULL surface with 0 index.
myWithTriangles is ignored for TopoDS_Face with NULL surface so that
triangulation-only faces are not lost with defaults.

Added Draw Harness command StoreTriangulation defining
WithTriangulation flag for BinXCAF/BinOcaf storage drivers.
