Nicolas Charpentier ee3532b5c2 Implement requiresMainQueueSetup in RCTTVNavigationEventEmitter
Summary:
Fix the following warning:

> Module RCTTVNavigationEventEmitter requires main queue setup since it overrides `init` but doesn't implement `requiresMainQueueSetup`. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

Trivial change.

[IOS] [MINOR] [RCTTVNavigationEventEmitter] - Implement `requiresMainQueueSetup` in `RCTTVNavigationEventEmitter`
Closes https://github.com/facebook/react-native/pull/16915
