New component with docs of a given component arguments

So, this is a feature request of sorts. Hopefully I'm able to describe what I would like to have from addon-docs.

So, auto generation of api documentation using JSDoc or ESDoc is great. I think we could use that to generate documentation of all the arguments that a component can take.

The problem I see today with the API docs section, is that usually I will have a documentation page for a component with several live demos. Having the documentation of the arguments of these components in a separated page is not the best experience. I would expect a "table" with all the available arguments for that component, having: `type`, `description`, `default value` and etc.

A great example of this is what @pranavliag is doing with [ember-elements](https://dunkinbase.github.io/ember-elements/docs). Here is [one example](https://dunkinbase.github.io/ember-elements/docs/core/tooltip#props).

I would like to have a component from addon-docs that I can use in one of my custom pages that would include the table with the documentation of the arguments. I would just pass the component name to it and it would take care of rendering that list of arguments.

We should also be looking forward to support glimmer components `args`. It will be interesting if folks are using TypeScript to define their arguments interface, then we can probably extract that info somehow.
