Debug Enso language in ChromeDev tools with --inspect option (#3432)
Finally this pull request proposes `--inspect` option to allow [debugging of `.enso`](e948f2535f/docs/debugger/README.md) in Chrome Developer Tools:

```bash
enso$ ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --inspect --run ./test/Tests/src/Data/Numbers_Spec.enso
Debugger listening on ws://127.0.0.1:9229/Wugyrg9Nm4OUL9YhzdcElmLft71ayZW3LMUPCdPyNAY
For help, see: https://www.graalvm.org/tools/chrome-debugger
E.g. in Chrome open: devtools://devtools/bundled/js_app.html?ws=127.0.0.1:9229/Wugyrg9Nm4OUL9YhzdcElmLft71ayZW3LMUPCdPyNAY
```
copy the printed URL into chrome browser and you should see:

One can also debug the `.enso` files in NetBeans or [VS Code with Apache Language Server extension](https://cwiki.apache.org/confluence/display/NETBEANS/Apache+NetBeans+Extension+for+Visual+Studio+Code) just pass in special JVM arguments:
```bash
enso$ JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,address=8000 ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --run ./test/Tests/src/Data/Numbers_Spec.enso
Listening for transport dt_socket at address: 8000
```
and then _Debug/Attach Debugger_. Once connected choose the _Toggle Pause in GraalVM Script_ button in the toolbar (the "G" button):

and your execution shall stop on the next `.enso` line of code. This mode allows to debug both - the Enso code as well as Java code.

Originally started as an attempt to write test in Java:

* test written in Java
* support for JUnit in `build.sbt`
* compile Java with `-g` - so it can be debugged
* Implementation of `StatementNode` - only gets created when `materialize` request gets to `BlockNode`
