feat(quartz): notify_quartz reusable workflow + dispatcher

[cgoea]

Cherry-pick of ROCm/TheRock@60c2a4f

Summary

First step of porting the Quartz CI-reporting scripts from ROCm/Quartz-Tester
into TheRock. This adds the self-report bridge that lets a TheRock workflow
push its run status to Quartz for ingestion.

• .github/workflows/notify_quartz.yml (new): reusable workflow_call
  workflow. Mints a Quartz Hauly GitHub App token and invokes the dispatcher.
  continue-on-error: true so reporting never fails the calling workflow.
• build_tools/github_actions/notify_quartz.py (new): stdlib-only
  dispatcher. Builds a payload for the current run (resolved via
  GITHUB_RUN_ID + the Actions API) and dispatches it to a Quartz ingest
  workflow via workflow_dispatch, at run start (run_phase=started) and
  end (run_phase=completed). Derives the run conclusion from a
  toJSON(needs) blob when no explicit conclusion is passed, and strips the
  inline jobs array (setting fetch_jobs) when the payload would exceed
  GitHub's 65,535-char dispatch-inputs cap. Targets ROCm/Quartz by default
  (override with --quartz-repo / QUARTZ_REPO).
• build_tools/github_actions/tests/notify_quartz_test.py (new): stdlib
  unittest coverage for the dispatcher's pure logic: reporting-path
  normalization (_normalize_reporting_path) and payload path overrides
  (_build_payload). Runs standalone, no network or GitHub API needed.

Copied from Quartz-Tester main except the pinned action SHAs, which were
bumped to match TheRock's current pins (actions/checkout v6.0.3,
actions/create-github-app-token v3.2.0), and the default ingest target,
which was switched from ROCm/Quartz-Tester to ROCm/Quartz.

References

• https://github.com/ROCm/Quartz/issues/17
• RFC: RFC0011-Quartz-CICD-Datahub.md,
  background on what Quartz is and why we report CI/CD data to it.
• Quartz Implementation Plan, the issue tracker. Note: it's not fully up to
  date.

Notes

• These files are standalone; they only become active once
  notify_quartz jobs are actually added to the workflows (a follow-up).
• Requires repo secrets GH_APP_HAULY_ID / GH_APP_HAULY_PRIVATE_KEY
  (Quartz Hauly GitHub App), already installed in TheRock.

just a plain cherry pick of ROCm/TheRock@60c2a4f

[marbre]

Should this have been ROCm/TheRock in our TheRock repository? Here rockrel is fine for sure, just noticed as you said it is a 1:1 port.

[marbre]

If this is a copy and also duplicates notify_quartz.py as well as the test, why don't we call into ROCm/TheRock/.github/workflows/notify_quartz.yml@main instead of duplicating?

[HereThereBeDragons]

right let me rework. might have been too naive to just cherry pick it

[marbre]

Okay, please re-request a review once you have it. Should be a quite little PR in the end.

closing. will reuse the notify_quartz code from therock
