Summary:
Rewrites `NativeEventEmitter` to not extend `EventEmitter` and to compose `RCTDeviceEventEmitter` instead of (mis)using its exported `sharedSubscriber` property.
This makes it easier to reason about `NativeEventEmitter`. Also, the extraneous methods on `EventEmitter` are no longer inherited.
Changelog:
[General][Removed] - `NativeEventEmitter` no longer inherits from `EventEmitter`, so it no longer implements `removeListener` and `removeSubscription`. Instead, use the `remove()` method on the subscription object returned by `addListener`.

Summary:
Simplifies the implementation of `DevSettings`. The fact that it uses `NativeEventEmitter` is an implementation detail and does not need to be exposed via inheritance.
This also enables more code to be removed from production builds (because the development implementation is now statically enclosed by `__DEV__`).

Summary:
Migrates all usages of `NativeEventEmitter` to `NativeEventEmitter<$FlowFixMe>`.
This prevents having to modify a very large number of files in the same change that adds support for typed events. It adds an unused typed parameter to `NativeEventEmitter` so we can change all usages to add `$FlowFixMe`.

Summary:
I wanted to configure the RN dev menu without having to write native code. This is pretty useful in a greenfield app since it avoids having to write a custom native module for both platforms (and might enable the feature for expo too).
This ended up a bit more involved than planned since callbacks can only be called once. I needed to convert the `DevSettings` module to a `NativeEventEmitter` and use events when buttons are clicked. This means creating a JS wrapper for it. Currently it does not export all methods, they can be added in follow ups as needed.
## Changelog
[General] [Added] - Export the DevSettings module, add `addMenuItem` method
Pull Request resolved: https://github.com/facebook/react-native/pull/25848
Test Plan:
Tested in an app using the following code.
```js
if (__DEV__) {
DevSettings.addMenuItem('Show Dev Screen', () => {
dispatchNavigationAction(
NavigationActions.navigate({
routeName: 'dev',
}),
);
});
}
```
Added an example in RN tester
