Add Shampoo optimizer support for neural network training in SystemDS.
Includes full-matrix and diagonal preconditioning, momentum updates, and a
heuristic variant with delayed preconditioner updates / infrequent root
recomputation. Extend the existing NN training scripts with tests to validate
correctness and convergence.
