Summary:To support native modules in web workers, native modules need to have an notion of the JS executor/thread that called into them in order to respond via Callback or JS module call to the right executor on the right thread.
ExecutorToken is an object that only serves as a token that can be used to identify an executor/message queue thread in the bridge. It doesn't expose any methods. Native modules Callback objects automatically have this ExecutionContext attached -- JSModule calls for modules that support workers will need to supply an appropriate ExecutorToken when retrieving the JSModule implementation from the ReactContext.

Summary: Now that web workers are just JSCExecutors, we can move forward with adding native module support. The means we need to supply the worker with a correct __fbBatchedBridgeConfig global so it can appropriately set up its JS MessageQueue. Unfortunately, native modules can't support multiple JS execution contexts out-of-the-box, so we need to whitelist those modules that actually can be referenced from a webworker. In order to do that, we add the supportsWebWorkers call in NativeModule and the SupportsWebWorkers annotation for JS modules. These add metadata to __fbBatchedBridgeConfig which allows us to create a new config with only those modules that support web workers.

This is an early release and there are several things that are known
not to work if you're porting your iOS app to Android.
See the Known Issues guide on the website.
We will work with the community to reach platform parity with iOS.
