    monitor-manager: Don't introspect "monitor-privacy-screen-changed"
    
    It passes a MetaLogicalMonitor, which isn't introspected right now, so
    skip it completely. The entry point to the UI is handled via
    MetaDisplay, so it isn't needed.
    
    This fixes the following warning:
    
    <unknown>:: Warning: Meta: (Signal)monitor-privacy-screen-changed: argument object: Unresolved type: 
'MetaLogicalMonitor'
