Summary: This diff ended up being a bit more complicated than I anticipated, since the source files in `ReactInternal` were depending on `RCTEventDispatcher`. I made the following changes: 1. Make `RCTEventDispatcher` a `protocol`, keep it in `ReactInternal`. 2. Rename the `RCTEventDispatcher` NativeModule to `RCTEventDispatcherModule`, make it conform to the `RCTEventEmitter` `protocol`, and move it to `CoreModules`. 3. Where necessary, replace categories of `RCTEventDispatcher` with functions. Changelog: [iOS][Added] - Make RCTEventDispatcher TurboModule-comaptible Reviewed By: fkgozali Differential Revision: D18439488 fbshipit-source-id: b3da15c29459fddf884519f33b0c3b8c036b5539
