[Audiosharing] Handle device volume when volume bar is changed without touch

Fix volume control when user use talk back swipe up/down or use Switch Access to change the volume bar progress Fix: 357028436 Fix: 357028435 Test: atest Flag: com.android.settingslib.flags.enable_le_audio_sharing Change-Id: Iab7d48ab8713a3a809cc8f7b28381a2b86b9be5f
