### How?

### What?
This PR introduces a ground work to generate wasm bindings package from
our napi bindings. This doesn't actually replace anything yet, however
aim to establish our napi bindings package can be built against wasm32
target.
### Why?
We currently have two bindings package to generate native / wasm target
support, one for napi and one other for wasm. Recently napi-rs started
to support to generate bindings for the wasm directly - which means we
can get rid of the wasm-pack based bindings code entirely and maintain a
single bindings code only.
This'll makes our `next-swc` simpler as well, since the invocation to
the bindings now becomes identical we don't have to additional wasm
specific logics to invoke functions (i.e transform, transformsync..).
Also napi generates wasi-supported wasm bindings, provides few more
features to the current wasm bindings.
#### Good
- Async napi binding fn works transparently (`transform`, `minify`...)
- (Experimental) thread supports depends on node.js runtime
- Wasi support: i.e it can even read filesystem directly!
#### Things to consider
- node.js's wasi support is experimental yet
- napi-rs's wasm support is in beta yet, specifically `packaging`
generated wasm output.
Due to `things to consider` reasons, this PR does not replace existing
wasm target yet. We should be able to plan out things later.
**What happens to the turbopack api in napi bindings?**
Simply put, this **does not support turbopack in wasm**. Build works by
disabling turbopack (more notably, underlying dependency doesn't support
wasm) features. It is something to explore separately.
Closes PACK-2367
There is a branch at https://github.com/vercel/next.js/pull/61586 shows
quick demo for importing, running sync / async / read external files.
# Turbopack

### What?
Update swc crates
### Why?
Required for #57718.
`styled-jsx` crate now has a hook to transform CSS code using a
Rust-side API
### How?
Fixes#57718
Closes PACK-2256
## What?
Implements https://github.com/vercel/turbo/pull/7081. Ensures image
imports in the edge runtime have the correct asset url. Previously it
would be `/assets/file.hash.png` but it should be
`/_next/static/media/file.hash.png`.
Updates the image tests to correctly compare the values in Turbopack and
the values in Webpack. Currently it only checks webpack values, causing
the tests to fail in Turbopack.

Closes NEXT-2194
### Description
This PR refactors existing `analysis/get-static-page-info`, moves over
most of parse / ast visiting logic into next-swc's rust codebase. By
having this, turbopack can reuse same logic to extract info for the
analysis. Also as a side effect, this removes JS side parse which is
known to be inefficient due to serialization / deserialization.
The entrypoint `getPageStaticInfo` is still in the existing
`get-page-static-info`, only for extracting / visiting logic is moved.
There are some JS specific context to postprocess extracted information
which would require additional effort to move into.
Closes PACK-2088
## What?
Skip postcss config resolving in node_modules for Turbopack. This
matches current Next.js on webpack closer as that only resolves the
postcss config from the project root. The additional feature Turbopack
has is that it can find a postcss config relative to the css being
compiled. This is useful for e.g. reducing the amount of overhead
certain postcss plugins that only have to run against a single file take
(i.e. Tailwindcss).
Depends on github.com/vercel/turbo/pull/7012 landing first.

### What?
This PR refactors organization for the rust side packages to build
`next-swc`.
### Why?
We had some historical legacy around package structures, have ambiguous
name for `core` / `next-core`. One contains swc transform visitor for
the next.js, and the other one is new for turbopack's core next.js
features. In addition to that, there was a package dependency chain
prevents to use `core` in the turobpack / next-swc both, so each time
porting a transformer into turbopack it requires to extract new
dependency to be imported in the both place.
PR touches its organization - while PR is large to touch various files,
the crux is summarized at
2cedd06ea5
:
1. `core` becomes `next-custom-transforms`, also this becomes an
agnostic pkg can be imported in turbopack / wasm / next-swc
2. simplify dependency chain to import next-custom-transforms, organized
as below
```mermaid
flowchart TD
C(next-custom-transforms) --> A(napi)
C(next-custom-transforms) --> B(wasm)
D(next-core) --> A(napi)
E(next-build) --> A(napi)
F(next-api) --> A(napi)
C(next-custom-transforms) --> D
D(next-core) --> F(next-api)
D(next-core) --> E(next-build)
```
`impl CustomTransformer` for the each transform still lives in
`next-core`, so turbopack specific dependency is isolated under
`next-core/build/api`.

### What?
Turbopack does not apply same transform for the react server components,
which makes missing lot of compilation error validation and custom
comments. PR refactors transform to be used in next-swc / turbopack
both, then apply it into turbopack.
There are still some of test cases are not passing, might need further
digging for the transform condition.

### 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
* https://github.com/vercel/turbo/pull/6713 <!-- Tobias Koppers - use
real emojis -->
* https://github.com/vercel/turbo/pull/6728 <!-- Tobias Koppers - fix
order of reverse topologic iteration -->
Closes PACK-2115
### What?
Bump up turbopack which includes url rewrite related improvements. This makes `test/integration/url` test passes.
Note there are some lacking behavior around edge runtime + url behavior, it is being tracked in PACK-2014.
Closes PACK-2051
### What
Pairing with https://github.com/vercel/turbo/pull/6602, enables
ecma-related transform support in mdx. notably fixes test cases in
https://github.com/vercel/next.js/pull/58968 .
With turbopack side fix, still modularize imports are not being applied
as we limite it to .js* extension only. PR expands it to include mdx if
mdx is enabled. PR is failling until turbopack side fix lands.
Closes PACK-2045

### What?
Various fixes in handling of externals in node.js
* add extensions to builtin externals to allow node.js ESM to work
* improve the auto-externals logic to detect more edge cases
* prepare for `esmExternals` support, but that's blocked by client
manifest missing the async flag
* currently only `esmExternals: false` is supported

### What?
We are experimenting with `lightningcss`. This is about replacing
`swc_css` with `lightningcss` in turbopack, and the main reason for this
is to reduce the maintenance burden.
But when I tried, it introduced several regressions, so I'm putting it
behind an experimental flag.
You can enable `lightningcss` mode for **turbopack** by adding a flag to
the next config file.
```js
/**
* @type {import('next').NextConfig}
*/
const nextConfig = {
experimental: {
useLightningcss: true,
},
}
module.exports = nextConfig
```
Note that this is only for turbopack because we were not using `swc_css`
for non-turbopack mode of next.js

We should avoid regressions.
