This allows us to pick GLX on X11 and EGL on Wayland at runtime when building with wxWidgets 3.3.2+ GLEW only allowed to choose between GLX/EGL at compile time. This also removes KICAD_USE_EGL option, KiCad will use whatever wxWidgets was built with. Fixes https://gitlab.com/kicad/code/kicad/-/issues/20647
