refactor: Refactor DeviceManager and related classes to improve thread safety and performance

- Replaced CCriticalSection with lock statements in DeviceManager for better thread management.
- Updated AddDevice and RemoveDevice methods to use Monitor for locking.
- Enhanced event handling for device activation and registration.
- Modified FileIO class to utilize Task for asynchronous file operations instead of CrestronInvoke.
- Improved feedback mechanisms in FeedbackBase and SystemMonitorController using Task.Run.
- Refactored GenericQueue to remove Crestron threading dependencies and utilize System.Threading.
- Updated BlueJeansPc and VideoCodecBase classes to use Task for asynchronous operations.
- Cleaned up unnecessary critical sections and improved code documentation across various files.
