Add plural fragment support to observeFragment() (#4862)

Summary: This PR adds plural fragment support to `observeFragment()` (and `waitForFragmentData()` which uses `observeFragment()` under the hood) It should be noted that the Relay environment currently doesn't support subscribing to plural fragment updates, so the implementation is done by subscribing to each selector and merging the states. Since the current implementation doesn't do any batching of notifications that are made from each selector subscription, it can be somewhat inefficient if the consumer doesn't batch on their own.
