patch 9.2.0501: GTK4: there is no GTK4 UI available

Problem:  GTK4: there is no GTK4 UI available
Solution: Implement GTK4 UI (Yasuhiro Matsumoto).

To enable, use the --enable-gui=gtk4 configure switch. Configure
currently favors GTK3 over GTK4 if no explicit --enable-gui switch has
been given and both libraries are present

closes: #19815
