  To: igt-dev, Lionel G Landwerlin

Add following changes to enable perf tests on TGL
- Support only a single OA format
- Add TGL metrics
- Update whitelist test case
- Cleanup mi-rpc test if it fails
- Skip unsupported test - gen8-unprivileged-single-ctx-counters

v2: Remove error cleanup in mi-rpc
