Remove 'reference_compile' from config.json

Hello!

## Pull Request overview
* Remove 'reference_compile' from config.json

## Details
This is a bit of an issue on the `transformers` side - the `reference_compile` should be adaptively set on the user's environment, rather than being set based on the model config.
