Currently, we are transitioning to the AppLifecycleState.detached incorrectly. This is causing the framework to stop pumping frames when the app is still active and visible.

This PR re-implements the transition to AppLifecycleState.detached as documented here (based on whether the app has any views or not).

Fixes flutter/flutter#150636
Fixes flutter/flutter#149417

Is this fix going to be cherry-picked for the next hotfix?

I'm eagerly waiting for this, as the current stable version 3.22.2 is rendering my application useless in some user cases (no new frames with active and visible application).
