[vtkusers] Ray intersection testing on GPUs for Surface meshes

[David E DeMarle]

I do not think this exists in VTK.

We don't have an interface to OptiX and the vtkEdge GPGPU work wasn't similar.

The simplest path to adding it is probably through the
Accelerators/Piston module which I just committed to VTK master last
week.
