These changes allow to open the exported project in XCode and Run it
immediately to begin debugging. Before these changes you'd have to
sign GDNative libs and change Build Configuration manually.
Now that #12009 is merged, we should let the system find the binary on
the users $PATH and don't assume we know where to look for them in
different distributions.
- The export process now builds complete .ipa on macOS, instead of just
creating XCode project.
- The project includes Capabilities games usually require: Game Center,
Push Notifications, In-App Purchase.
- Icons and launch screens can be specified in export preset.
