Export more solid-js types

[thetarnav]

These types are useful for library development. Otherwise they have to be imported like this:

import type {
  ResolvedJSXElement,
  ResolvedChildren,
  ContextProviderComponent,
} from "../node_modules/solid-js/types/reactive/signal.js";

So it makes sense to export them unless they are mean to be internal only.
