[swift-corelibs-dev] Implementing JSONSerialization.jsonObject(with stream)

[Philippe Hausler]

We had changed the return type of JSONSerialization to be Any such that it avoided the caller needing to bridge types (which works poorly on linux). Even though this is an API change technically, just change the return type to match the other JSONSerialization methods.
