feat: add optimization tests

• depends on test(linter): allow disabling optimizations oxc#13735

Adds an extra check to ecosystem to run oxlint with/without optimizations turned on. They are turned on by default, but we want to try running with them off to ensure that the diagnostic count emitted is exactly the same.

I think it'd be better to use --format=json, parse the output and then assert that the actual diagnostics are identical rather than just relying on the count

@camc314 Yeah I had considered that at first, but didn't want to go too deep into this before getting some feedback. I can update this to use the JSON output though, I think we just need to make sure the diagnostics are sorted first and it should be okay.
