[ROCm] Version-tier S3 layout, standardized CI
job naming, and nightly build workflow
Version-tier S3 artifact layout:
- Add rocm-release-version tier to S3 artifact
paths to prevent wheel collisions across ROCm
versions.
- Add per-repo/branch/version LATEST pointer for
wheel resolution.
- Parameterize manylinux container image in
build_rocm_artifacts.yml.
- Plumb s3_download_uri through bazel_rocm.yml.
Standardize CI job naming and matrix schema:
- Unify ROCm matrix entries across all caller
workflows to use a canonical schema with label,
wheel-version, release-version, and tag fields.
- Update job names to use matrix.rocm.label.
- Add rocm-release-version input to pytest_rocm,
bazel_rocm, and download-jax-rocm-wheels to
decouple wheel filename matching from S3 path
construction.
- Add manylinux-image input to
build_rocm_artifacts so callers can override
the container image.
Nightly workflow:
- Add a dedicated build-rocm-artifacts job to
the nightly workflow that builds wheels with
pinned XLA (clone_main_xla: 0) and uploads to a
nightly-specific S3 path.
- Update nightly pytest and bazel ROCm jobs to
depend on the new build.
