Turbopack: Emit whether server or client assets changed (#53879) ### What? Updates the new `entrypoint.changed()` method to signal whether the server or client assets changed. Now, a `{ changed: 'server' | 'client' | 'both' }` will value will be yielded by the subscription. ### Why? So that client-only changes can be handled differently than server-only changes. ### How? We just needed to track the server and client output assets separately, so that we can detect changes to either individually. It's difficult to tell what `Vc` change triggered a recomputation on the Rust side (I'd have to involve mutable `State` into the Vc), and it's also hard to re-emit a duplicate value (eg, if a client change follows a client change, we need 2 emits). Instead, I tie the two different `server_changed()` and `client_changed()` functions into a single enum on the TS side. Depends on https://github.com/vercel/next.js/pull/53809, since I don't want to introduce merge conflicts while Tobias is on vacation.
