Refactor Steam Networking Components

- Removed SteamMessageHandler class and its implementation files.
- Integrated control packet handling directly into the SteamMessageHandler.
- Updated TCPClient and TCPServer classes to improve connection management and error handling.
- Added SteamNetworkingManager class to manage Steam networking, including lobby creation and connection handling.
- Implemented callbacks for Steam Friends and Matchmaking to handle lobby events.
- Enhanced message forwarding logic between TCP clients and Steam connections.
- Introduced control packet handling for ping responses.
- Improved thread safety with mutexes for shared resources.
