Discussion
Use this method on the main thread to measure an extended launch task. Your app needs to start the first task before or during scene(_:restoreInteractionStateWith:), or before the system calls sceneDidBecomeActive(_:) on the first scene to connect, and each task needs to overlap with others.
The maximum number of tasks is 16. The extended launch measurement finishes when all running tasks finish.
