fix: remove unavailable EventEmitter TS export (#36109)

Summary:
currently, using TS, this is a valid import:

`import { EventEmitter } from 'react-native';`

However, looking at the [index file](https://github.com/facebook/react-native/blob/main/index.js) we can see that there is no such export.

I first thought I'd add the EventEmitter export in order to get the `index.js` in line with the types, but it appears that the Event Emitter will become a separate package at some point #34401 so removing it from the types seems to be better for future.

Pull Request resolved: #36109

Test Plan: tested locally: using `import { EventEmitter } from 'react-native';` correctly gives `TS2305: Module '"react-native"' has no exported member 'EventEmitter'.`
