This reducer takes a good chunk of the bundle but is never run on the server so we can eliminate it. 5-10ms wins from my manual benchmark runs.

This PR adds the benchmarking script I've been using for #40251 to
measure the performance improvements that we make to the Edge SSR
runtime.
This tool:
- uploads two version of the benchmarking project to Vercel, one with
the latest canary and the one with your current local changes in dist
(don't forget to build!)
- runs some tests against the published url to measure TTFB
- displays a nice chart and table
What this doesn't do (yet):
- allow you to choose which URL to compare
- allow you to change the measured metric
- run a battery of differnet test

As per #40926 we commit all node_modules inside test so we can test external packages. It will be much more convenient to not hide them in VS Code. With this configuration, all node_modules folders will be excluded except for these under the test directory.

Since React 18 returning `undefined` from components is allowed which renders to `undefined` in the RSC response so we need a separate prop to know if the loading boundary was provided.

We currently resolve the `react-server` condition correctly inside
`externals` for the server layer, however that will cause the resolved
path to be external (as it is called "externals").
So we need a way to hook into the module resolution process to force it
to use the `react-server` condition **when it's on the server layer**.
The `resolve` option doesn't give us that ability, and the solution in
this PR is to leverage `normalModuleFactory`'s resolve hook to override
the resolve options before actually resolving it. And there we can have
the `contextInfo`.
One thing left out is bundling for the edge server, we need to add tests
and sort that out carefully.

Currently, a developer building a website using Next.js could write this
code with no type errors:
```tsx
<Image
width="kangaroo"
height="100px"
quality="medium"
{...rest}
/>
```
This PR adds stricter type checking, which will catch this type of error
earlier.
Similarly, this PR adds stricter types for the `responseLimit`, to
ensure the types align to:

# Context
Edge SSR'd routes cold boot performances are proportional to the
executed code size.
In order to improve it, we are trying to optimize for the bundle size of
a packed Edge SSR route.
This PR adds ESM compilation targets for all Next.js dist packages and
use them to bundle Edge SSR'd route.
This allows us to leverage the better tree shaking/DCE for ESM modules
in webpack in order to decrease the overall bundle size.
This PR also enables minifying Edge SSR routes. Since we don't control
which minifier might be used later (if any), it's best if we provide an
already optimised bundle.

This is a 10ms cold boot win per my benchmarking script, which I'll put
in a subsequent PR.
Not done yet:
- ~~swap exported requires in `next/link` (and others) etc to point them

### Issue
When import an esm package in client component, and use it in server
component page, it will fail to SSR but render successfully on client.
It's because the import to esm package will make the client chunk become
an **async module** since esm module will be treated as **async**.
```
page (serve component) -> local module (client) -> external dependency (esm)
```
Then in react SSR layer, it need the module type information of that
chunk, async or not for react so that react could unwrap the async
module from `Promise` properly when SSR.
### Solution
We need to mark the client entries which are effected by async/esm
modules that becoming **async** as `async: true` in SSR manifest.
Since flight manifest plugin is only running against client compiler,
which doesn't have those module information from server compiler. So we
collect the async modules from the **server** compiler **client** layer
from flight entry client plugin, then leverage the collection to detect
if a module is async in flight manifest plugin for react.

When navigating from app to pages, we do a flight render on the server
to generate the redirected path. However due to our new bundling
strategy we can't use the bundled `ComponentMod.renderToReadableStream`
because the component is now a regular component, not a RSC. In that
case we have to import the unbundled flight server.

This updates to ensure we properly error during static generation when a
non-dynamic SSR error is thrown so that unexpected errors are not
tolerated. This also fixes the static generation async storage not being
shared correctly due to different instances being created during
bundling.
