Add notification volume controller in settings

Separate notification and ring controllers based on the ring/volume
stream alias boolean in config.xml.

For both ring and volume controller: Not show vibrate icon when vibration is not supported on device. Show
silent icon instead.

Known issue: Add the notification volume slider only in Settings, and
not in VolumePanelDialog. When the alias is set to false and the streams
separated, the ring volume slider in VolumePanelDialog keeps its title
of "Ring & notification volume" instead of changing to "Ring volume".

Bug: b/38477228
