Subject: Audio Routing support in UI

Changes:
- AudioModeProvider - receives audio mode changes from
  CallHandlerService
- CallButtonPresenter listens to AudioModeProvider so that it can use
  those changes in the UI.
- CallButtonFragment uses the audio mode from Presenter() to display:
   - The correct layers for the supported modes
   - The popup menu when bluetooth is enabled
