Feature request: support Apple TV

[douglowder]

Describe the Feature

I'm the maintainer for the Apple TV and Android TV RN repo (https://github.com/react-native-tvos/react-native-tvos). I'd like to implement better CLI support for Apple TV with two features:

• New command react-native run-tvos (this can be done with the right flags to run-ios, but it would be convenient to have a separate command)
• Make react-native upgrade work with the react-native-tvos fork

Possible Implementations

I plan on implementing these, but wanted to find out your preference on the approach I should take.

For run-tvos, should I make changes to the existing platform-ios package, or do it in a separate package (which means a lot of duplicate code)?

For upgrade, it seems to me the right way is to have upgrade.ts detect that the project uses react-native-tvos and use the react-native-tvos diffs (I have already created a repo for the diffs). But if you prefer a separate command or package for this, that's ok.

CLI has a plugin subscription mechanism that allows npm packages to expose their own plugins. This way react-native-tvos can expose a run-tvos plugin, that uses platform-ios under the hood (any changes to make it more generic so it fits tvos needs better are welcome!). Check this doc: https://github.com/react-native-community/cli/blob/master/docs/plugins.md.

Regarding upgrade, it's not super reliable for the default template. If the change would be a simple switch to change the source of the diff, then I think we can put this in for now. And later figure out something similar to CLI plugins so this repo doesn't have to maintain too many templates.

Thanks for the tips, I'll do run-tvos inside the RN TV repo, and see if the change for upgrade can be done here in a not too intrusive way.

Fixed in release 6.1.0
