feat: add APU-P1 support and enhance test coverage

- Introduced new task  in  for handling high-performance APU writes with access fault checks.
- Updated  to support an expanded resource count, including ownership and IRQ routing for the new APU resource.
- Enhanced  to validate IRQ expectations for the newly added APU resource.
- Created  for directed verification of APU-P1 APB4 register shell and integrated IRQ ownership topology.
- Added  to ensure synchronization between RTL and SDK register ABI.
- Modified  to parameterize tests for product modes, improving flexibility in testing.
- Updated  to reflect changes in APU memory mapping and ensure correct assertions.
- Enhanced  to validate the complete IRQ and resource allocations for the APU.
