Refactor new tether settings to remove SharedPreferences

Browse Source 
Bluetooth, USB and Wifi Disable tether preferences will turn on/off that
type of tethering interface instantly without storing it into
SharedPreferences. They are listening to TetherEnabler to update their
state.
Refactored to remove dependancy on SharedPreferences.

Bug: 151367756
Test: TetherEnablerTest; BluetoothTetherPreferenceControllerTest;
UsbTetherPreferenceControllerTest;
