Convert DeviceInfoSettings into a dashboard fragment.

This is needed to use logging from DashboardFragemnt.
This page is now a mixture of PrefernceController and non-controller
preferences.

Also permanently removed system update preference from xml to simplify
migration

Todo: convert the rest of preference into controller.

Bug: 34774945
Test: make RunSettingsRoboTests
