This PR enhances arith simplify to handle symbolic reshape patterns. Lift the CombineIters to callers of TryFuseIters so they can be used in early return simplifications. Testcases are added. Also updates a minor spelling issue in the testcase.

This commit resolves a flaky test failure that was introduced in apache#15081. The unit test `tests/python/unittest/test_meta_schedule_schedule_rule_mlt_tc.py::test_padded_matmul_relu` failed approximately 30% of the time. The error was due to changes in `IterMapRewriter::NormalizeToIterWithOffset`. When attempting a simplfication with `TryCombineSplitFromSameSource`, if the returned `Optional<IterSumExpr>` is defined, but the `args.size() < 1` check fails, then the `expr` argument is still overwritten, and presumably can cause a later `TryFuseIters(expr)` to fail. This commit replaces `expr = opt.value();` with `auto combined = opt.value();`, preserving the original argument.
