[Paraview] Using CUDA accelerated vtkm filter

[Robert Maynard]

Hi,

The "caught ErrorBadDevice: Device with id 2 is either not in the list
or is invalid."  is thrown from VTK-m when somebody has asked to
execute on the CUDA device adapter ( with id == 2 ) and components of
VTK-m have been built without CUDA enabled. The device id has nothing
to do with which specific GPU VTK-m will use.

As for where this mismatch in compiling with CUDA support is
occurring, somebody from the VTK-m team will look into it.
