Refactor audio codec and display messaging interfaces

- Introduced IDialerCallStatus interface to streamline call status handling in audio codecs.
- Updated AudioCodecBase to implement IDialerCallStatus, providing a common structure for call status events.
- Added IDisplayCurrentInput interface for display devices to expose current input information.
- Created corresponding messenger classes for IDialerCallStatus and IDisplayCurrentInput to facilitate communication.
- Implemented CameraControlMessenger for camera devices to manage camera controls and presets.
- Added IWarmingCoolingMessenger for warming and cooling devices to handle status updates.
- Updated MessengerFactoryRegistry to register new messenger classes and ensure proper device messaging.
- Cleaned up CameraBase and removed unnecessary comments and whitespace in various files.
