0025129: Visualization - add interactive object for Points Cloud objects

Browse Source 
New class AIS_PointCloud for displaying point sets.
Update Graphic3d_ArrayOfPoints, OpenGl_PrimitiveArray and OpenGl_VertexBuffer classes to be able to use normals for points.

Add Draw Harness command vpointcloud.
Add test case v3d/point_cloud/sphere.

Move protected method AIS_Shape::DisplayBox() to public function StdPrs_WFDeflectionRestrictedFace::AddBox().

Small correction of grids.list for v3d tests
