0027919: Visualization - support multiple transformation persistence groups within single presentation

Browse Source 
Added transform persistence property to Graphic3d_Group and Select3D_SensitiveEntity.
SelectMgr_ViewerSelector, Graphic3d_Layer and OpenGl_Structure have been updated
to process per-group transform persistence within picking, ZFit and rendering.

Added zoomable state to Prs3d_ArrowAspect supported by PrsDim_Dimension.

Added gp_GTrsf::SetMat4(), opposite to gp_GTrsf::GetMat4().
