Andrew Clark 83643778bd Internal test helpers: Use Node's MessageChannel to queue task (#26345)
To wait for the microtask queue to empty, our internal test helpers
schedule an arbitrary task using `setImmediate`. It doesn't matter what
kind of task it is, only that it's a separate task from the current one,
because by the time it fires, the microtasks for the current event will
have already been processed.

The issue with `setImmediate` is that Jest mocks it. Which can lead to
weird behavior.

I've changed it to instead use a message event, via the MessageChannel
implementation exposed by the `node:worker_threads` module.

We should consider doing this in the public implementation of `act`,
too.

scheduler

This is a package for cooperative scheduling in a browser environment. It is currently used internally by React, but we plan to make it more generic.

The public API for this package is not yet finalized.

Thanks

The React team thanks Anton Podviaznikov for donating the scheduler package name.
