Pull Request Overview
This PR adds a new Graph_GetModelPath API function to the ORT Graph API that allows execution providers to retrieve the file path of the ONNX model. This is particularly useful for execution providers that need to load EPContext models (compiled models) and determine the path to EPContext node binaries.
Key changes:
- Added
Graph_GetModelPathfunction to the C API that returns the model's file path - Implemented the function across all graph type implementations with appropriate fallbacks
- Added comprehensive test coverage for the new functionality
