Notification settings UI on Oreo or later

* On devices with Android 8.0 (Oreo) or later, use system UI to change notification settings.
* Refactor sound selection code to cover differences between old (pre Oreo) and new devices.
* Always use the same notification channel for calls (Oreo or later).
