vtkIOSSReader: add API to expose block ids
vtkIOSSReader now has API that users can use to determine block ids based on block names. This is useful in case blocks have special names which then ends up hiding their block ids. Needed to address paraview/paraview#16883 (closed).
ParaView MR for testing: paraview/paraview!5661 (merged)
