After #8467, Engine benchmarks are broken, they cannot compile - https://github.com/enso-org/enso/actions/runs/7268987483/job/19805862815#logs
This PR fixes the benchmark build
# Important Notes
Apart from fixing the build of `engine/bench`:
- Don't assemble any fat jars in `runtime/bench`.
- Use our `TestLogProvider` in the benches instead of NOOP provider.
- So that we can at least see warnings and errors in benchmarks.
