0024406: Visualization - crash on re-usage of the same primitive array

Redesign Graphic3d_ArrayOfPrimitives
Store vertices data in buffer objects managed using smart-pointers
- no more low-level memory corruption by memory releasing after VBO creation.
Remove broken hasEdgeInfos.

Interleave vertex attributes (position, color, normal, uv) in single buffer.
Remove from Graphic3d_ArrayOfPrimitives methods ::Orientate().
Remove structures Graphic3d_PrimitiveArray, CALL_DEF_PARRAY.
Add support for 2D vertex arrays.

Graphic3d_Group - remove array or primitive arrays.
Introduce more universal method Graphic3d_Group::AddPrimitiveArray().

Fix warning
