feat: Add new messengers for various device interfaces and remove VideoCodecBaseMessenger

- Implemented IHasMeetingInfoMessenger to handle meeting information updates.
- Created IHasReadyMessenger for devices indicating readiness status.
- Added IHasStandbyModeMessenger to manage standby mode actions.
- Introduced IPrivacyMessenger for privacy mode control.
- Developed IVideoCodecInfoMessenger to provide codec information.
- Removed the obsolete VideoCodecBaseMessenger class.
- Updated MessengerFactoryRegistry to register new messengers for IHasReady, IHasMeetingInfo, IHasStartMeeting, IHasStandbyMode, IPrivacy, and IVideoCodecInfo interfaces.
