Proposal: Add support for shallow rendering

[IgnusG]

Inferno adapter could replace the contents of the component with null which prevents its rendering.

It could then redirect methods which try accessing its internal props, state ... to the host node instead of the rendered nodes (which would be null).

I'm not sure about the implications to lifecycle methods though. Theoretically inferno unmounts a component once it returns null so I would suspect componentWillUnmount and/or componentDidMount not firing predictably.

Have to cross-check with preacts adapters

I'm happy to take a PR for this, but I won't work on this myself.

No worries, mostly putting it here so I don’t forget the approach. I’m gonnna try implementing it later
