Model saved by ORT as external data format will not be aligned for mapfile support

[ivberg]

Describe the issue

ORT has the ability to save a model with external data format - https://github.com/onnx/onnx/blob/main/docs/ExternalData.md

However, this model will not be aligned and mapfile support will not work - #21195

To reproduce

session_options.SetGraphOptimizationLevel(ORT_DISABLE_ALL); // ORT_DISABLE_ALL, ORT_ENABLE_BASIC, ORT_ENABLE_EXTENDED, ORT_ENABLE_ALL: // Ideally the model would be saved with basic or higher optimization level. However, there is a related bug on this OnnxRuntime 21325 -Model saved with offline basic optimizations will not load – ShapeInferenceError

    session_options.SetOptimizedModelFilePath(optimized_model_path);
    session_options.AddConfigEntry(kOrtSessionOptionsOptimizedModelExternalInitializersFileName, "model.quant.extdata.disable_opt.onnx.data");
    session_options.AddConfigEntry(kOrtSessionOptionsOptimizedModelExternalInitializersMinSizeInBytes, "10");

    session = Ort::Session(env, filemodelpath_base_unencrypted, session_options);

Urgency

Low urgency. There is the ability to add alignment in Python in PR - https://github.com/onnx/onnx/pull/6248
