* Refactor GEMM tests to use parameterized pytest fixtures

- Converted multiple test cases for GEMM operations in `test_tilelang_tilelibrary_gemm_sp.py` to use `pytest.mark.parametrize` for better maintainability and readability.
- Similar refactoring applied to `test_tilelang_tilelibrary_gemm_sp_v2.py`, consolidating test cases for `run_gemm_ss`, `run_gemm_rs`, `run_gemm_sr`, and `run_gemm_rr` into parameterized tests.
- This change reduces code duplication and enhances the clarity of test configurations.

* Update testing/python/amd/test_tilelang_gemm_mfma_preshuffle.py
