macos: Remove old NSApp workaround related code
This is no longer needed since the introduction of `gst_macos_main()` in 1.22. Before that existed, we had a patch for GLib in Cerbero, which did work but made it impossible to update GLib at all. The code being removed was a fail-safe in case of running without said patch being applied. It's no longer needed, since for macOS we just wrap our GStreamer with an NSApplication using `gst_macos_main()`. Warnings will be displayed if no NSApp/NSRunLoop is found wherever needed, pointing the user towards using the new API.
