Bring back `COverdrawPolygonGeometryOptimizer` from `COverdrawMeshOptimizer`

Description

Bring back the overdraw optimizer.

Description of the related problem

Since ICPUMeshBuffer got completely refactored

Solution proposal

Now ICPUPolygonGeometry supports any geometry (a bit of a misnomer cause its a VertexGeometry really, lines and points are included).

But the zeux algorithm works on clusters, so I think working on quads, etc. shouldn't be that different from just triangles.

Additional context

A large OBJ or STL/PLY is needed to make an example
