Took an initial stab at warning about string refs within a strict tree.

There are a couple of things I feel uncertain about:

  • What's a better/more informative warning message than the one I wrote?
  • Is the approach of deduping based on the returnFiber display name reasonable?
  • For the time being, I've linked fb.me/react-strict-mode-string-ref to a little blurb in our current documentation. Where should I link it, long term?

Resolves #12158. Relates to #1373.

👍The returnFiber approach seems fine.

Thanks for confirming!

Any suggestions on the wording of the warning? Okay for now?
