refactor: refactor tests to replace RIBP references with APB4 equivalents

- Updated test files to change instances of ribp_if to apb4_if in various test cases, ensuring consistency with the new APB4 interface.
- Modified assertions and checks in tests to reflect the new APB4 naming conventions, including changes in expected output and input files.
- Adjusted the test descriptions to accurately represent the APB4 functionality being tested, particularly in timer, UART, and GPIO tests.
- Ensured that all relevant paths and file names in the tests are updated to point to the new APB4 implementations, maintaining the integrity of the test suite.
