Add diagram for Flutter lifecycles to Lifecycle Events page

Would be nice to have a page dedicated to both internal flutter lifecycles and platform lifecycle events with diagrams.

The internal stuff is already at https://docs.flutter.dev/ui/widgets-intro#responding-to-widget-lifecycle-events. Could just re-summarize visually.

The page is https://master-docs-flutter-io.firebaseapp.com/flutter/dart-ui/AppLifecycleState-class.html We should definitely add suitable diagrams to that page though.

Do we link to AppLifecycleState from /widgets-intro ?

I don't know but we certainly should! :-)

Might still be worth having an 'editorial'/'guide' style page like Android/iOS have in https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/TheAppLifeCycle/TheAppLifeCycle.html, https://developer.android.com/guide/components/activities/activity-lifecycle.html besides the API references

More correct link to API doc: https://docs.flutter.io/flutter/dart-ui/AppLifecycleState-class.html
