Use `derive-builder` in the runner crate

The `javy-runner` contains a builder that reconciles all the CLI options and therefore it has grown (and will continue to grow) to contain a wide range of fields. As per @surma's suggestion, we could consider using the `derive-builder` crate to reduce some of the boilerplate.
