[SYSTEMDS-3259] Implementation of the shampoo optimizer (initial prototype)
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. Tests: src/test/scripts/applications/nn/component/shampoo_test.dml src/test/scripts/applications/nn/component/shampoo_test2.dml src/test/scripts/applications/nn/component/shampoo_test.py Experiments in staging/shampoo_optimizer
