Mathieu Fenniak 0ecc6ef632 fix(actions): improve errors when ${{ needs... }} is used in strategy.matrix incorrectly (#10298)
Three fixes are presented together in this PR:
- When a `strategy.matrix` entry in an Action job contains `${{ needs.some-job.outputs.some-output }}`, if that output *never* becomes available, different error messages will be presented if `some-job` isn't found or if `some-output` isn't found.  This clarifies an error message that was previously "it could be this, or it could be this".
- In the error case described in the previous point, other jobs in the workflow could continue running or could be left "blocked" forever.  A centralized `FailRunPreExecutionError` function ensures that all incomplete jobs in the run are failed in this case.
- In a rare error case when a job referenced another job in `strategy.matrix` but no other jobs were defined in the workflow, the job would be marked as blocked forever because the `job_emitter` code would never be invoked to detect this case.  A new `consistencyCheckRun` function for a newly created `ActionRun` adds a location to perform a pre-execution check for this case so that the run can be failed.

These fixes are all interconnected around the refactor for the `FailRunPreExecutionError`, causing them to be bundled rather than individual PRs.

  - [ ] in `web_src/js/*.test.js` if it can be unit tested.
  - [ ] in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)).

### Documentation

- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
