GtkInfoBar is a final class in GTK4, which we cannot derive from. For single-child widgets like EvMessageArea, libadwaita provides AdwBin, which is the GTK4 equivalent to GtkBin. Deriving EvMessageArea from GtkBin now simplifies the GTK4 move. Relates #1864 Relates !373 Co-authored-by: Qiu Wenbo <qiuwenbo@kylinos.com.cn>
