Turbopack: switch to a single client components entrypoint (#59352)

### What?

switch turbopack to use a single client components entrypoint for all
client components on a page for development. This aligns it with the
webpack behavior.

### Why?

compiling a separate entrypoint for every client component is pretty
expensive in regards of compilation, chunking, code generation, file
writing and number of requests.

### Turbopack Changes

* vercel/turborepo#6713 <!-- Tobias Koppers - use
real emojis -->
* vercel/turborepo#6728 <!-- Tobias Koppers - fix
order of reverse topologic iteration -->


Closes PACK-2115
