Status icons in component list

The problem

No idea which items in the component list are new, deprecated, or under development/experimental. A good example would be GitHub's guide: https://styleguide.github.com/primer/

Proposed solution

Update ComponentsListRenderer to display the status based on docblock tags, like @new, @deprecated, and @experimental. Tag descriptions would be shown in a tooltip.

Alternative solutions

N/A

Additional context

I'm testing this currently by overriding SG components. Will report back.
