feat: Add ci-barretenberg-full CI mode

## Summary
- Adds a new `ci-barretenberg-full` CI mode triggered by the `ci-barretenberg-full` label
- Runs the full `barretenberg/bootstrap.sh ci` instead of just `barretenberg/cpp/bootstrap.sh ci`
- This builds and tests all barretenberg components: cpp, ts, rust, acir_tests, sol, and docs

## Test plan
- [ ] Merge this PR first (using `ci-full` or default mode)
- [ ] On subsequent PRs, use the `ci-barretenberg-full` label to trigger full barretenberg CI
