Add AppLifecycleListener, with support for application exit handling (#123274)
## Description
This adds `AppLifecycleListener`, a class for listening to changes in the application lifecycle, and responding to requests to exit the application.
It depends on changes in the Engine that add new lifecycle states: https://github.com/flutter/engine/pull/42418
Here's a diagram for the lifecycle states. I'll add a similar diagram to the documentation for these classes.
## Related Issues

## Tests
- Added tests for new lifecycle value, as well as for the `AppLifecycleListener` itself.
