0029729: Visualization, Graphic3d_ClipPlane - add support of clipping plane chains

Browse Source 
Graphic3d_ClipPlane now can define a Chain of Planes (logical AND).
OpenGl_ShaderManager - added new GLSL sub-programs for clipping plane chains.
Bnd_Range::TrimFrom(), ::TrimTo() - added auxiliary methods for trimming the range.
SelectMgr_ViewClipRange now handles non-continuous clipping range.
Graphic3d_SequenceOfHClipPlane now aggregates NCollection_Sequence instead of inheritance.
OpenGl_CappingPlaneResource - triangulation has been adjusted to make front face following CCW order.
