Refactor to create a core package

[krispya]

We want to refactor to create a core package along with packages targeting specific renderers such as react-three-fiber. From user level, a single renderer package can target multiple versions automatically by detecting their package.json. In this case the react-three-fiber package will target v8 or v9 based on detection. Internally, we will keep them as separate packages, if possible, for clean typing.

How do you imagine different renderers interplaying with the editor itself? What is in core, the ast manipulation, service, editor ui? Is the use case to handle more webgl based renderers or web as well?

I believe Nikhil has plans to try and support anything that can be represented as React component. A refactor was already done with ecc24d0, but for this to be considered closed we will need to complete some kind of support for v8/v9 packages.
