this file was in common/, but I think we should not have a common/ directory
because it is confusing with the usual meaning of "common" in Chrome which means
"shared by the browser and the renderer".

I'm following the pattern of test_browser_state here and put the implementation
in public/.
Let me know if you want me to move it out of public.

Honestly I'm not really clear on when content/ puts impls in public/, so I don't
have a good answer either way. I'm fine doing whatever seems consistent for now,
and we can revisit later if it becomes an issue.
