[Reland2] Implements UISceneDelegate dynamically w/ FlutterLaunchEngine (#169276)

Browse Source 
## **BREAKING CHANGE**

Adopting Apple's UISceneDelegate protocol shifts the initialization
order of apps. For the common cases we've made sure they will work
without change. The one case that will require a change is any app that
in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]` assumes that
`UIApplicationDelegate.window.rootViewController` is a
`FlutterViewController` instance. This is sometimes done to register
platform channels directly on the `FlutterViewController`. Instead users
should use the `FlutterPluginRegistry` API's to create platform channels
in `-[UIApplicateDelegate didFinishLaunchingWithOptions:]`, like
`FlutterPlugin`s do.

An example can be seen here:

https://github.com/flutter/flutter/pull/168914/files#diff-9f59c5248b58124beca7e290a57646023cda3ca024607092c6c6932606ce16ee

In extreme cases, like bespoke test harnesses, the startup logic can be
moved to `-[FlutterViewController awakeFromNib]` in a
FlutterViewController subclass.

An example can be seen here:

https://github.com/flutter/flutter/pull/169276/files#diff-dbe39c23a0a380447b90b7559a878dae8564616e0875c4ef0d9e99e02b91adac

## Changes since revert
I changed the init in `//dev/integration_tests/external_textures` from
the UIApplicationDelegate to the FlutterViewController's awakeFromNib.
This is a more appropriate place for initialization post-UISceneDelegate
since it avoids the launch engine altogether. I tried avoiding to make
the big change to prove we could do a small change to migrate that
project. I don't think this big refactor is indicative of what users
will experience. There was a timing assumption in the integration test
that required not using the launch engine at all.
