Update Settings text styles to use DeviceDefault.

- Replace all TextAppearance.Material styles with the equivalent
TextAppearance.DeviceDefault style
- Reparent Theme.Settings.HomeBase to inherit from Theme.Settings. This
ensures that the correct textAppearance theme attributes are applied
throughout the Settings application.
