[nautilus/gtk4-preparation-trunk: 36/46] toolbar: Don't subclass HdyHeaderBar




commit 3f1ee0ad7b45d49cafaba3a378da3606264d9486

    toolbar: Don't subclass HdyHeaderBar
    
    In GTK4 we are not going to be able to subclass headerbars.
    
    But subclassing GtkWidget directly implies adding a lot of
    boilerplate to behave as a container.
    
    The easy way around that is going to be AdwBin. Use GtkBin for the
    time being, but introduce a wraper for a missing method.
