Allow multiple readers to iterate over a stream at the same time

### What is the problem this feature will solve? When multiple callers use [`Readable[Symbol.asyncIterator]`](https://github.com/nodejs/node/blob/4c3e9659ed116e610d8da8aa0b692cc8c6abb6e4/lib/internal/streams/readable.js#L1336), each caller receives a partial result. ```js import {Readable} from 'node:stream' const stream = Readable.from(['a', 'b', 'c']) const iterate = async (readerName) => { for await (const chunk of stream) { console.log(readerName, chunk) } } await Promise.all([ iterate('one'), iterate('two'), ]) ``` ``` one a two b one c ``` Some callers might expect that result. But others might expect the following result instead. ``` one a two a one b two b one c two c ``` ### What is the feature you are proposing to solve the problem? Adding an option to `readable.iterator()` to use `readable.on('data')` instead of `readable.read()`. This would enable the above behavior. ### What alternatives have you considered? Implementing this user-land. See an example of it at https://github.com/sindresorhus/get-stream/pull/121
