report error when using "use server" on module level (#47967)

### What?

Add a error message when using "use server".

* vercel/turborepo#4477 <!-- Tobias Koppers - add
ServerDirective transform which reports unsupported -->


### Why?

Turbopack doesn't support "use server" yet.

### Other turbopack updates

* vercel/turborepo#4464 <!-- Justin Ridgewell -
Better dotenv error messages -->
* vercel/turborepo#4485 <!-- Justin Ridgewell - Add
ServerAddr::hostname method -->
