0027816: Visualization - provide an API for overriding clipping planes list

Browse Source 
Graphic3d_SequenceOfHClipPlane now inherits Standard_Transient.
PrsMgr_PresentableObject, Graphic3d_Structure, Graphic3d_CStructure,
V3d_View, OpenGl_View now manages the plane list by Handle.
The getters ::GetClipPlanes() has been removed,
setters taking non-handle ::SetClipPlanes() has been marked deprecated.

OpenGl_Structure::Render() and SelectMgr_ViewerSelector::checkOverlap()
now disable global (view) clipping planes for objects
with flags Graphic3d_TMF_TriedronPers and Graphic3d_TMF_2d
or with new flag Graphic3d_SequenceOfHClipPlane::ToOverrideGlobal().

OpenGl_Clipping now implements interface for managing clipping planes
without copying the sequences.
The filtering of duplicates is no more performed by OpenGl_Clipping
- application is responsible to not do this.
OpenGl_Clipping tries avoiding unnecessary allocations for managing
list of active planes.

MFC sample has been updated to use V3d_View::ClipPlanes() method.
