feat: refactor NMI to RIB Interface and Update Related Tests

- Replaced instances of nmi_if with rib_if in sysctrl_fault_tb.sv, test_dma.py, test_gpio_user_mux.py, test_memory_map.py, test_performance_log.py, test_script_tools.py, test_sdram.py, test_soc_topology.py, test_sta_constraints.py, and test_user_extensions.py.
- Updated test cases to reflect changes from NMI to RIB, ensuring all references and assertions are consistent with the new interface.
- Adjusted memory map and performance log tests to validate RIB-specific configurations and behaviors.
- Ensured that all relevant file paths and definitions are updated to maintain functionality and correctness across the test suite.
