Expand DRA Driver Integration for GPU Operator

[karthikvetrivel]

Purpose

This PR builds on Chris's DRA integration work in #1541 and serves as the umbrella integration branch for NVIDIA DRA driver support in GPU Operator.

It includes both:

• updates needed to align GPU Operator with newer DRA driver assets, CRDs, RBAC, and image layout
• follow-on GPU Operator features required to make DRA support usable and maintainable across supported deployment modes

Change Log

48c2079:

• Refreshed the embedded DRA driver manifests to the newer driver layout: split kubelet-plugin RBAC/service accounts, updated controller/kubelet-plugin workloads, removed the old entrypoint ConfigMap, and wired the newer DRA image.
• Updated DRA CRD packaging: refreshed ComputeDomain, added ComputeDomainClique, included them in Helm CRD hooks, Dockerfile packaging, and the OLM bundle.
• Updated GPU Operator reconciliation support for the new assets: handling multiple Role objects, applying new DRA transforms, and adjusting tests for the refreshed DaemonSet/Deployment structure.
