Print out warnings associated with local variables (#10842) 
Fixes #9749 by:
- [x] Adding `fn` option to `enso-debug-server` instrument - eb3b76e
- [x] Print warnings (if any) to stderr - 4fda04b
- [x] Improving output of `:list` to print out warnings - dbe3c45480
- [x] Print errors to stderr - 1312546
- [x] Exiting on `DataflowError` - 2cc7ef5 and e6fbf73
- [x] Using all of that inside of `runner/*Main` - 7df58ef

The core of the change is in instrumentation that wraps the `main` method and at its end checks for _warnings or errors_ among local variables. When an error is found, it wraps the original return value of `main` with a proxy that delegates to the original value, but also pretends to be _exit exception_ with exit code 173. That one is detected in `Main` launcher to exit the process with exit code 173.

# Important Notes
As a side-effect of this change, one can request an invocation of REPL at the end of any method just by providing a property to the VM:
```bash
$ enso --vm.D=polyglot.enso-debug-server.method-break-point=err_test.main --run err_test.enso --repl
```
stops at the end of `main` method of `err_test.enso` file.
