    session: stop saving window role in the session state
    
    Apparently, when running under X11 it is possible to tell GTK to restore
    particular windows on particular workspaces. That's cute, but I don't
    like X11-specific code, and it's gone in GTK 4. We'll have to remove
    this in the future no matter what, so might as well get rid of it now.
