Wrap two more variants of vtkCellData::SetData.

The only variant of vtkCellData::SetData() (which took vtkDataArrays) was not working well because of its implementation. It makes shallow copies of its arguments even when they are of the right type which causes issues with memory management when the data comes from numpy (because vtkDataArrayPython is the object that holds a reference to the numpy object not the underlying buffer object).
