Refactor the PrepareCoordinator and related components to improve the handling of reference specifications in the TTS system. Introduce new methods for building and extracting reference prompts and specifications, along with detailed profiling metrics for performance monitoring. Update the PrepareRefSemanticBatchWorker to include additional timing metrics and caching mechanisms for resampling. These changes enhance the efficiency and maintainability of the TTS framework, particularly in managing audio processing and reference data.
