0025180: Visualization - Homogeneous transformation API in TKV3d

Browse Source 
PrsMgr_PresentableObject, Graphic3d_Structure now consistently
take and store Handle(Geom_Transformation) instead of
TColStd_Array2OfReal / Graphic3d_Mat4.
Low-level advanced methods have been modified to pass Handle(Geom_Transformation).
High-level methods have been preserved accepting old syntax taking gp_Trsf.

Geom_Transformation now inlines most methods.
