Pull request overview

This PR adds an AITK workflow/recipe to optimize and evaluate Stable Diffusion v1-5 using OpenVINO (Intel CPU/GPU), including new Olive pass configuration for OpenVINO IO updates and encapsulation, plus model registry/runtime updates.

Changes:

• Add an OpenVINO workflow (sd_ov_workflow.py + JSON + UI .json.config) and register it in the model project metadata.
• Extend per-submodel Olive configs to include OpenVINOIoUpdate + OpenVINOEncapsulation and adjust UNet example inputs for static shapes.
• Update OpenVINO saving logic to emit a Diffusers ONNX pipeline layout, and update the global model list to include Intel CPU/GPU runtimes for SD v1-5.
