0024291: Visualization - move Z-buffer trihedron presentation from TKOpenGl to TKV3d

Not implemented method V3d_View::TriedronEcho() and enum Aspect_TypeOfTriedronEcho have been removed.
The following methods have been removed from Graphic3d_CView class:
TriedronDisplay(), TriedronErase(), ZBufferTriedronSetup(), TriedronEcho().
New class V3d_Trihedron has been added as replacement of removed OpenGl_Trihedron
which now uses Graphic3d_TMF_TriedronPers persistence.
