feat: add RTC wake functionality and related integration

- Introduced  signal in sysctrl interface and module to handle RTC wake events.
- Added RTC wake status register in memory map and updated related tests.
- Integrated RTC wake handling in the APB wrapper and core wrapper.
- Enhanced clock and reset domain configurations to include RTC signals.
- Updated software build configurations to include RTC source files and headers.
- Modified formal verification and testbench files to accommodate RTC wake functionality.
- Ensured proper synchronization and status recording for RTC wake events in the sysctrl module.
