In order to have useful Wayland builds we need ability to switch between GL backends run-time - to use EGL backend for Wayland and GLX backend for X11. GL_PROVIDER_GLX is used exclusively for GLX GL backend, so let's replace GL_PROVIDER_GLX build-time check by more general MOZ_X11 check which determines X11 dependent code and it's valid for both X11 and Wayland builds.
