Summary: TurboModule methods that return promises are synchronously run on the JavaScript thread. Back in D22489338 (https://github.com/facebook/react-native/commit/9c35b5b8c4710dfe6a4b689a5565aa78ae5b37d3), we wrote code to make them dispatch on the NativeModules thread. That code, however, was just left disabled. In this diff, I wire up the TurboModules infra to a MobileConfig, which should allow us to assess the performance impact of async dispatch of promise methods to the NativeModules thread in production, before we roll it out more widely. Changelog: [Internal] NOTE: This diff was reverted, beacuse we landed it it without D24685387.
