Extract duplicate part for hearing audio routing into SettingsLib
Similar functions need to be called when hearing device get connected, so move them into SettingsLib. Bug: 269122580 Test: make RunSettingsRoboTests ROBOTEST_FILTER=HearingDeviceAudioRoutingBasePreferenceControllerTest Change-Id: I15296fb81726c96c1d2fec7397e981e71e305450
