Provide a way to identify kind of MenuItem

[ultimaweapon]

The standard location for About and Settings on macOS is on the application menu itself:

On other platforms About is an item on the Help menu and Settings is either an item on the File or Edit menu. In order to put those MenuItem in the application menu we need to identify if it is About or Settings. AFAIK currently the only way to identify if MenuItem is either About or Settings is checking its text, which is not good so it would be great if we have a better way for this.

We were thinking adding a role property to MenuItem to move item to the app menu.

enum MenuRole {
    none,
    app-menu-quit, // this replaces implicitly created quit item
    app-menu-preferences,
    app-menu-about,
    app-menu // all those go into the app menu at the top
}

But this hasn't been implemented yet

Can we convert this discussion to an issue according to #8408 since it is a feature request?
