    app-system: Add back StartupWMClass matching
    
    While unfortunate that we still have to scan all apps with get_all(),
    support for this feature will be short-lived, so hopefully we can drop
    it in the future as new apps adapt to the desktop file / app ID
    recommendations.
    
    For now, simply scan all desktop IDs.
