onnxruntime-genai based metadata and packaging

• Added support for packaging models (and additional files) generated by the GenAIModelExporter. Also, updated the pass configuration to include search parameters that are forwarded to the generated genai_config file.
• Added support for carrying "additional files" from one pass to next. These files will end up in the generated models output folder and will be packaged.
• Two new packaging configuration options -
  • include_sample_code
  • inlcude_runtime_packages

Release Note:

Packaging config include two new options -

• include_sample_code - whether or not to include sample code in zip archive. Defaults to true.
• include_runtime_packages - whether or not to include runtime packages (like onnxruntime) in zip archive. Defaults to true.
