Add command-line options for cppcheck to the CI job: - `--suppress=constParameterCallback` - `--check-level=exhaustive` information: Limiting analysis of branches. Use --check-level=exhaustive to analyze all branches. - `--force` information: Too many #ifdef configurations - cppcheck only checks 12 configurations. Use --force to check all configurations.
