Describe the Feature Request

class and interface documentation generated along with props documentation.

Describe the Use Case

As a developer consuming a web component library built with StencilJS I would like to see the component documentation (from its class or interface) when hovering its markup.

Describe Preferred Solution

// my-interface.ts

/**
 MyInterface Docs
*/
interface MyInterface {

   /**
    prop Docs
   */
   prop: string;
}

// my-component.tsx
export class MyComponent implements MyInterface {
   // ...
}

// consuming the lib

<my-component prop={"hello world"} />

When hovering <my-component> I should be able to see the class/interface documentation.
