Extract idb device querying to IOSBridge

Summary:
Again this is just a code move for now.

However, we now have a common method between simctl and idb cases. This means that the next diff can call an `IOSBridge` with polymorpism taking over. This is still delegated out, but there's an argument to be made to move `iosUtil` functionality back so that this all lives in the same place.
