0031505: Point Cloud Rendering - fix on-screen statistics about number of visible...

OpenGl_Element now provide methods ::UpdateMemStats() and ::UpdateDrawStats()
for unified request of statistics used by OpenGl_FrameStats instead of direct handling of OpenGl_PrimitiveArray.
Graphic3d_FrameStatsCounter counters list has been extended by Graphic3d_FrameStatsCounter_NbLinesNotCulled.
