major(core): forward ref by default

[JoviDeCroock]

This removes the ability to get a component instance assigned to the ref, instead we will preserve ref on props for functional components and assign for normal DOM nodes. In the start I wanted to preserve props.ref entirely but that would make us access props.ref quite a lot which would be megamorphic access as well as need a new condition during element diffing.

I left the base tests untouched as we are removing component.base anyway in #4356. During this implementation I realised that if we're able to derive that a VNode comes from a JSX transform that we could stop cloning in compat VNode props handling which would safe a lot of memory.
