Add settings VR listener service.
Bug: 22855417 Bug: 26724891 - Adds a settings panel allowing users to toggle the enabled/disabled state of each VrListenerService component installed. - If disabled, a VrListenerService will not be bound from the framework, even when requested by a VR application. Change-Id: I606eb712c011d160b9fbdd3c0e8fd744c653ef07
