- Update preference key to match the key defined in SettingsSlicesContract - Model TwoStateButtonPreference similar to TwoStatePreference (add setChecked, isChecked method) - Remove TwoStateButtonPreferenceController entirely because all methods are moved into Preference directly for better encapsulation. - Make BatterySaverButtonPrefController direclty implement TogglePreferenceController. It was not possible before because the interface between TwoStateButtonPreferene is too different from TwoStatePreference.
