Mathieu Fenniak 75cb38faa6 feat: support reusable workflow expansion when with or strategy.matrix contains ${{ needs... }} (#10647)
This change allows the `with:` field of a reusable workflow to reference a previous job, such as `with: { some-input: "${{ needs.other-job.outputs.other-output }}" }`.  `strategy.matrix` can also reference `${{ needs... }}`.

When a job is parsed and encounters this situation, the outer job of the workflow is marked with a field `incomplete_with` (or `incomplete_matrix`), indicating to Forgejo that it can't be executed as-is and the other jobs in its `needs` list need to be completed first.  And then in `job_emitter.go` when one job is completed, it checks if other jobs had a `needs` reference to it and unblocks those jobs -- but if they're marked with `incomplete_with` then they can be sent back through the job parser, with the now-available job outputs, to be expanded into the correct definition of the job.

The core functionality for this already exists to allow `runs-on` and `strategy.matrix` to reference the outputs of other jobs, but it is expanded upon here to include `with` for reusable workflows.

There is one known defect in this implementation, but it has a limited scope -- if this code path is used to expand a nested reusable workflow, then the `${{ input.... }}` context will be incorrect.  This will require an update to the jobparser in runner version 12.4.0, and so it is out-of-scope of this PR.

## Checklist

The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org).

### Tests

- I added test coverage for Go changes...
  - [x] in their respective `*_test.go` for unit tests.
  - [ ] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- I added test coverage for JavaScript changes...
  - [ ] 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)).
- **end-to-end test:** will require the noted "known defect" to be resolved, but tests are authored at https://code.forgejo.org/forgejo/end-to-end/compare/main...mfenniak:expand-reusable-workflows-needs

### 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.

### Release notes

- [ ] I do not want this change to show in the release notes.
- [x] I want the title to show in the release notes with a link to this pull request.
- [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.
