ci(tidb): migrate peer-binary downloads to OCI helper (#4336)

Part of #4341
Closes #4342

## Summary
- move the `tidb` integration e2e, lightning, and BR jobs from
source-repo download scripts to
`${WORKSPACE}/scripts/artifacts/download_pingcap_oci_artifact.sh`
- compute OCI tags per component in Groovy and keep the BR / lightning
auxiliary artifacts and TiFlash layout handling aligned with the OCI
helper flow
- add the missing `utils` containers to the affected pod templates so
the migrated OCI-helper based jobs can run in both merged and release
branches
