Add a way to create Server Reference Proxies on the client (#26632)

This lets the client bundle encode Server References without them first
being passed from an RSC payload. Like if you just import `"use server"`
from the client. A bundler could already emit these proxies to be called
on the client but the subtle difference is that those proxies couldn't
be passed back into the server by reference. They have to be registered
with React.

We don't currently implement importing `"use server"` from client
components in the reference implementation. It'd need to expand the
Webpack plugin with a loader that rewrites files with the `"use server"`
in the client bundle.

```
"use server";

export async function action() {
   ...
}
```
->
```
import {createServerReference} from "react-server-dom-webpack/client";
import {callServer} from "some-router/call-server";

export const action = createServerReference('1234#action', callServer);
```

The technique I use here is that the compiled output has to call
`createServerReference(id, callServer)` with the `$$id` and proxy
implementation. We then return a proxy function that is registered with
a WeakMap to the particular instance of the Flight Client.

This might be hard to implement because it requires emitting module
imports to a specific stateful runtime module in the compiler. A benefit
is that this ensures that this particular reference is locked to a
specific client if there are multiple - e.g. talking to different
servers.

It's fairly arbitrary whether we use a WeakMap technique (like we do on
the client) vs an `$$id` (like we do on the server). Not sure what's
best overall. The WeakMap is nice because it doesn't leak implementation
details that might be abused to consumers. We should probably pick one
and unify.

DiffTrain build for commit b600620.
