Complete iDynTree::Span and iDynTree::MatrixView SWIG typemaps

In https://github.com/robotology/idyntree/pull/1233 we added typemaps to automatically permit to methods that take in input a iDynTree::Span to take in input a `np.array` in Python. To complete these functionalities, we should also add typemaps for:

* [ ] iDynTree::MatrixView on Python
* [ ] iDynTree::Span on MATLAB
* [ ] iDynTree::MatrixView on MATLAB
