Frgaal integration in sbt (#3421)

* Initial integration with Frgaal in sbt

Half-working since it chokes on generated classes from annotation
processor.

* Replace AutoService with ServiceProvider

For reasons unknown AutoService would fail to initialize and fail to
generate required builtin method classes.
Hidden error message is not particularly revealing on the reason for
that:
```
[error] error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider com.google.auto.service.processor.AutoServiceProcessor could not be instantiated
```

The sample records is only to demonstrate that we can now use newer Java
features.

* Cleanup + fix benchmark compilation

Bench requires jmh classes which are not available because we obviously
had to limit `java.base` modules to get Frgaal to work nicely.
For now, we default to good ol' javac for Benchmarks.
Limiting Frgaal to runtime for now, if it plays nicely, we can expand it
to other projects.

* Update CHANGELOG

* Remove dummy record class

* Update licenses

* New line

* PR review

* Update legal review
