[AMD] Strip auto_map from Quark export for Phi-4 support

[poganesh]

Describe your changes

Workaround for Quark export not copying auxiliary files referenced by auto_map in config.json. For example, Phi-4-mini-instruct config references configuration_phi3.py and modeling_phi3.py via auto_map, but Quark doesn't include these files in the output causing onnxruntime_genai builder to fail when loading model.

Workaround until fixed in quark: strip auto_map from exported config.json post-export when trust_remote_code=False. This is safe because transformers natively supports these models via model_type (e.g., phi3) without needing custom code files. No impact on other models, it's a no-op if auto_map isn't present.

@xieofxie, @jambayk - This PR adds support for Phi-4-mini-instruct in Olive, with a workaround in Quark 0.11.

Could you please help review it.
