Add onnxruntime/capi to MIGraphX wheel runpath

[kentqian]

Summary

Add the sibling onnxruntime/capi directory to the packaged MIGraphX EP library RUNPATH.

libmigraphx-ep.so depends on the ONNX Runtime shared library, which is installed under site-packages/onnxruntime/capi. Without this path, plugin registration can fail in an isolated Python environment even when the onnxruntime dependency is installed.

🟢 Approval recommended

The change is a minimal, targeted RUNPATH update in the wheel-staging patch step that aligns with the documented site-packages layout and does not alter build logic beyond adding one additional lookup directory.

Pull request overview

This PR updates the MIGraphX EP wheel packaging logic to include the onnxruntime/capi sibling directory in the ELF RUNPATH for the staged MIGraphX EP shared library, ensuring it can locate the ONNX Runtime shared library from an installed onnxruntime Python package in isolated environments.

Changes:

• Add $ORIGIN/../onnxruntime/capi to the computed RUNPATH used when patching libmigraphx-ep.so (and related MIGraphX artifacts) during wheel staging.
