maksyuki 9c706ba0ff feat: refactor test scripts to update paths and improve organization
- Updated paths in test files to reflect new directory structure for RTL and script files.
- Changed references from rtl/mini to rtl/ip and scripts/rtl where applicable.
- Added a new test file for Tiny product isolation, ensuring independent ABI and bus acceptance.
- Enhanced tests for memory map generation and protocol contracts for Tiny architecture.
- Ensured that all tests are aligned with the latest directory structure and naming conventions.
