    preferences-row: Add a "title-selectable" property
    
    For the GTK4 port of Contacts, we're using `AdwPreferencesRow`s and
    `AdwActionRow`s.
    
    In previous versions, we just used a `GtkLabel` to present the row. We
    could then set the `"selectable"` property to TRUE, to deal with a major
    use case when people use Contacts: to actually copy info (like a phone
    number) into whatever other application they are using.
    
    With `AdwPreferencesRow` that's not possible, so this would be a
    regression.
    
    Fixes https://gitlab.gnome.org/GNOME/libadwaita/-/issues/300
