 * Workaround function to avoid circular dependencies between Launch and CommonUnixStartup modules.
 *
 * Other platforms call FEngineLoop::AppExit() in their main() (removed by preprocessor if compiled without engine), but on Unix we want to share a common main() in CommonUnixStartup module,
 * so not just the engine but all the programs could share this logic. Unfortunately, AppExit() practice breaks this nice approach since FEngineLoop cannot be moved outside of Launch without
 * making too many changes. Hence CommonUnixMain will call it through this function if WITH_ENGINE is defined.
