Refactor CosyVoice inference methods to streamline CUDA stream management

Browse Source 
- Removed the queue-based stream pool and integrated direct CUDA stream usage for improved performance.
- Simplified inference methods by eliminating unnecessary synchronization and stream management code.
- Enhanced logging for better tracking of synthesis operations and performance metrics.
- Updated the model class to support CUDA stream context management, ensuring efficient resource utilization during inference.
