This pull request adds support for the videochat_flash_qwen model in the OpenVINO exporter.

  • Added VideoChatFlashQwenOpenVINOConfig and related classes to handle configuration, dummy input generation, and export behaviors for the videochat_flash_qwen model. This includes support for multiple behaviors (language, vision embeddings, vision projection, text embeddings) and registration in the tasks manager.
  • Implemented VideochatFlashQwenLanguageModelPatcher and VideochatFlashQwenVisionEmbeddingModelPatcher to patch the model's forward methods for export, ensuring compatibility with OpenVINO requirements.
