Add RBAC manifest for E2E CI runner

Adds deployment/e2e-ci-runner-rbac.yaml which grants the Arc Runners
service account the minimum permissions to deploy/teardown an
E2E Headlamp instance in headlamp-dev (or privilegedescalation-dev
when E2E_NAMESPACE is overridden).

Note: polaris-plugin also needs the E2E_NAMESPACE in the workflow
env block changed to privilegedescalation-dev to match intel-gpu-plugin.

Fixes PRI-550.
