  [mlir][affine] Add folders for delinearize_index and linearize_index (#115766)

This commit adds implementations of fold() for delinearize_index and
linearize_index to constant-fold them away when they have a fully
constant basis and constant argument(s).

This commit also adds a canonicalization pattern to linearize_index that
causes it to drop leading-zero inputs.
