    a11y: Change default accessible role
    
    Only GtkWidget should use GTK_ACCESSIBLE_ROLE_WIDGET as its default
    accessible role; the default for GtkAccessible and GtkATContext should
    be GTK_ACCESSIBLE_ROLE_NONE, meaning "an element whose implicit native
    role semantics will not be mapped to the accessibility API", according
    to the WAI-ARIA specification.
