This commit adds the UseUserAccessGroup method to the Firebase C++ Auth SDK. This method is only functional on iOS and acts as a no-op stub on other platforms (Android, desktop). It wraps the [FIRAuth useUserAccessGroup:error:] Objective-C method on iOS, allowing C++ developers to specify a keychain access group for sharing authentication data between apps. Key changes: - Added UseUserAccessGroup to the public Auth class in auth.h. - Implemented the iOS-specific logic in auth_ios.mm. - Provided stub implementations in auth_stub.cc (for desktop) and auth_android.cc (for Android).

Desktop needs this too.
- Moved stub implementations from auth_stub.cc to auth_desktop.cc and auth_android.cc. - Removed auth_stub.cc. - Removed unnecessary forward declaration for UseUserAccessGroupInternal from auth.cc. - Added a basic integration test for UseUserAccessGroup to ensure it doesn't crash on any platform.
