Android App Archive support

[Marocco2]

Describe the feature

Android 15 app Archive feature can archive specific apps when not in regular use. When an app is archived, it removes its software, permissions, temporary files, and stops notifications, but retains the app icon and data.

Currently it's supported on Google Play Store, Accrescent and F-Droid nightly AFAIK.
This feature is very convenient as I don't want my installed apps to do something in the background but I want to keep their data stored. It's also better than Disabled state as it won't remove their icons on the AOSP launcher.

This is the reference implementation on Accrescent: accrescent/accrescent@b8517c4

Adding to this, it would be quite convenient to have an option to archive an app while keeping its APK file cached in Obtainium. That way, we can essentially "disable" (archive) an app while keeping its icon in the launcher and also the ability to quickly "re-enable" it (re-install) without an internet connection directly from Obtainium without third party disabler.

So an app can be in the following states:

App State	Not Run in BG	Keep Data	Keep Icon	Obtainium Support
Installed	✖️	✅	✅	✅
Uninstalled	✅	✖️	✖️	✅
Disabled	✅	✅	✖️	✖️
Archived	✅	✅	✅	✅

So we get all the benefits of disabiling an app + keeping the icon + being supported by Obtainium.

Edit: APK file caching would be an optional setting in Obtainium for people who want "true archiving" with the benefit of freeing space from the device at the cost of requiring internet connection to re-enable the app.
