feat: add watchdog (wdg) module integration and update related components

- Updated file lists to include new watchdog RTL files in clusterip.
- Replaced async_reqack source in commonip file list with top-level CDC file.
- Modified clock and reset domain configurations to incorporate watchdog reset signals.
- Updated the SoC topology generation script and JSON to reflect changes in watchdog interrupt handling.
- Added watchdog source files to software makefile for compilation.
- Enhanced APB wrapper to connect watchdog reset request signal.
- Updated RCU module to handle watchdog reset requests.
- Modified testbench to validate watchdog reset functionality.
- Updated test cases to reflect changes in interrupt naming conventions for the watchdog.
