CocoaLibEvent does not contain bitcode

After fresh setup according to docs, tvOS build encounters error:

ios/Pods/CocoaLibEvent/lib_tvos/libevent.a(event.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

CocoaLibEvent is something that Flipper seems to require, and I can’t find any proper info on how to enable bitcode for CocoaLibEvent pod.

If I comment out the references to everything related to Flipper in the Podfile, and comment out everything related to Flipper, the app runs.

Steps To Reproduce

1. npx react-native init MyApp --template=react-native-tvos@latest
2. Open Xcode to run on connected AppleTV 4K

The thing actually runs without adjustments, or at least a mention of this gotcha in the readme 😃

@olafurnsig A quicker way to get up and running on a device is to add a user defined setting to your project build settings:

ENABLE_BITCODE=NO

However, not doing the device build with Bitcode enabled might cause problems with submission to the App Store, so I’m going to have to think carefully about whether I should put this into the new project template.

@olafurnsig this is fixed in the 0.62.2 maintenance branch, and will be in the next release. I disabled Bitcode for debug device builds (Flipper is only supported for debug builds anyway).

If you are using the community CLI (@react-native-community/cli), you can try this by doing

react-native init TestApp --template=https://github.com/react-native-community/react-native-tvos#tvos-v0.62.2

Thanks for the hard work Doug!

But yeah, Bitcode is a requisite for a AppleTV release in the appstore, so it should only be disabled for debug builds.
