Stefan Brüns ab181ac329 highgui: Fix unresolved OpenGL functions for Qt backend ...

The Qt backend directly calls some OpenGL functions (glClear, glHint,
glViewport), but since OCV 4.5.5 the GL libraries are no longer part
of the global extra dependencies. When linking with "-Wl,--no-undefined"
this causes linker errors:

`opencv-4.5.5/modules/highgui/src/window_QT.cpp:3307: undefined reference to `glClear'`

Fixes: #21346
