Clean up the interface to the bridge
Summary: Change the following classes into interfaces, with a separate Impl file: CatalystInstance, ReactInstanceManager, CatalystQueueConfiguration, MessageQueueThread. This is done to help isolate the interface between React Native and applications which use it. This will also help some intrusive development work on a branch such as porting parts of the bridge to common C++ code, without affecting app reliability while this work is ongoing. public Reviewed By: astreet Differential Revision: D2651277 fb-gh-sync-id: f04dc04a6e68df7acbc2bbf8b2529287d7b5b2ae
