Add other app lifecycle events

[npvisual]

Let's see if we can bring in some / most of the events handled by UIApplicationDelegate, so we can handle deep links, user activities, etc.

After spending some time investigating the following resources :

• https://www.hackingwithswift.com/quick-start/swiftui/how-to-add-an-appdelegate-to-a-swiftui-app
• https://peterfriese.dev/ultimate-guide-to-swiftui2-application-lifecycle/
• https://vmanot.com/how-to-use-uiapplicationdelegateadaptor
• https://swiftui-lab.com/nsuseractivity-with-swiftui/

and running a few tests, it's appears that UIApplicationDelegateAdaptor might not be working as expected.
