CP: Pause UIScene migration (#170490) (#170569)
CP of https://github.com/flutter/flutter/pull/170490

This PR rolls back auto-migrating iOS apps to UIScene lifecycle. It also updates tests to ensure things work in both a state where UIScene lifecycle is already adopted and when it isn't.

A number of UIScene issues have emerged since landing this in master: https://github.com/flutter/flutter/issues/170171

In addition, there's is disagreement over how some of it is implemented.

Impacted Users: All Flutter iOS developers
Impact Description: Some method channels may crash and apps using app lifecycle events may not work properly.
Workaround: Manually removing UIApplicationSceneManifest from Info.plist and potentially also update AppDelegate.swift.
Risk: Low
Test Coverage: Yes
