    gdkglcontext-win32.c: Avoid C4715 warning
    
    We can just group the code for the desktop GL codepath and the EGL
    codepath a bit so that we can just have a single location where we
    return TRUE upon a successful setup of our WGL/EGL context, and avoid
    the C4715 warning that is considered an error when building with
    GLib-2.68.x or later using Visual Studio, when we are building without
    EGL support.
