0026199: Visualization - use NCollection_IndexedMap instead of NCollection_Sequence in OpenGl_BVHClipPrimitiveSet to improve performance

Browse Source 
This patch improves performance of OpenGl_BVHClipPrimitiveSet. In particular, on the attached test case for 90 000 spheres the results are the following:

1) Master: vdisplay - 55 sec, 5 FPS, 1.4 GB memory, vclear - 180 sec.
2) Branch: vdisplay - 1.3 sec, 5 FPS, 1.4 GB memory, vclear - 90 sec.

So, the patch improves vdisplay in ~40 times, and vclear in ~2 times without extra memory and with no impact on rendering performance. However, the vclear time is still significant. According to profile results, it is due to Graphic3d_Structure::DisconnectAll method.

Test case for issue CR26199

Fix invalid warnings in 'vdefaults' command.
