MapFieldOntoOutput is no longer public API. Since `vtkm::cont::Filter` invokes it when appropriate, we no longer need to keep it public. Also removes the overload of MapFieldOntoOutput that doesn't take policy. That is no longer needed since vtkm::cont::Filter always can provide the current policy being used.
