[gtkmm] Gtk: Remove API which has been removed in gtk+-4

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 1e33b58346a738b51cae01a2f2c6f6fc3b39c80e
Author: Kjell Ahlstedt <kjell ahlstedt bredband net>

    Gtk: Remove API which has been removed in gtk+-4
    
    * gtk/src/treeview.hg: Remove get_bin_window().
    * gtk/src/viewport.hg: Remove get_bin_window() and get_view_window().
    * gtk/src/widget.hg: Remove get_style_property_value() because
    gtk_widget_style_get_property() has been removed. Use the still existing
    gtk_widget_style_get() in get_style_property(). Remove declarations of
    the previously removed Gtk::Action and Gtk::Style classes.
