don't configure xdmf3 (i.e. IOParallelXdmf3) on 32-bit arches

where vtk's copy of xdmf3 fails to build. See Bug#1126484
upstream paraview Issue #22630
https://gitlab.kitware.com/paraview/paraview/-/issues/22630

Configuration of VTK::xdmf3 as an external library (libxdmf-dev builds
for all architectures) might resolve it, help welcome.

extra VTK modules support paraview. Closes: #1100766
