Separate component array types and command array types (#48474)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48474

The previous definition said that you could put prop types into commands, which definitely isn't allowed.

For example, the schema would have allowed `WithDefault` types.

```
interface NativeCommands {
  +methodInt: (viewRef: React.ElementRef<NativeType>, a: WithDefault<string, 'hi'>) => void;
}
```

This change separates out the things that are allowed in commands from what's allowed in props.

Commands should be very similar to what's allowed in native modules, but it isn't exact enough to be able to merge those.
