feat: Add support for dynamic matrix evaluation in Gitea Actions workflows (#36564)

Adds dynamic matrix evaluation to Gitea Actions: a job's
`strategy.matrix` can be built from the outputs of the jobs it needs.

```yaml
jobs:
  generate:
    runs-on: ubuntu-latest
    outputs:
      matrix: ${{ steps.set.outputs.result }}
    steps:
      - id: set
        run: echo "result=[1,2,3]" >> $GITHUB_OUTPUT

  build:
    needs: [generate]
    runs-on: ubuntu-latest
    strategy:
      matrix:
        version: ${{ fromJson(needs.generate.outputs.matrix) }}
    steps:
      - run: echo "building ${{ matrix.version }}"
```

Such a matrix cannot be expanded at planning time, so the job is planned
as a single placeholder and expanded by the job emitter once its needs
finish. Each combination is then gated by `if:` and concurrency as
usual.

- A matrix that resolves to no combination fails the job, as on GitHub.
- Expansion is capped at `MaxJobNumPerRun`.
- Workflows without a needs-dependent matrix are unaffected.

Fixes https://github.com/go-gitea/gitea/issues/25179
