core: add MitosisComponent.props

I think the code will be a lot simpler in the generators if we provide more metadata on the props. For example in angular we want to know if it's a function and if it's being invoked. or in React if it's going used in `ref` binding.

I was something something like
```typescript
type PropType =
| 'function'
| 'string'
| 'boolean'
| 'undefined'
| 'null';

// metadata on how it's being used
type PropUsed =
| 'binding'
| 'invoked'
| 'binding.ref' // forwardRef
| 'function'
| 'onMount'
| 'onInit'
| 'onUnMount'
| 'onUpdate'
| 'onUpdate.dep';

interface MitosisProp {
type: PropType;
used: PropUsed[];
code: string;
}
```

Locate the MitosisComponent definition and the generators that consume its props metadata. Review how props are currently represented, then determine whether the proposed type, usage markers, and source code are sufficient; done means generators can inspect this metadata for cases such as invocation and ref binding.
