Removes the `_` prefix from the RSC and Router headers as nginx strips
`_` prefixed headers by default.

Bundle the ssr client layer for RSC, this solves the problem when
there's an esm package is using on client components, but esm imports
the installed react instead of the built-in react version since esm
imports is not intercepted by require hook.
After bundling the ssr client layer and treating react as externals, now
react compiles as cjs externals and could be intercepted by require
hook, other code are bundled together which can also get optimized.

This ensures we don't stub `react-dom` with the `experimental-edge` runtime and also unpins our tests to use the latest experimental release.

Makes it possible to switch between edge/server runtime in dev without
breaking the server.

#### middleware-plugin.ts
`middlewareManifest` moved from module scope to local scope. Stale state
from earlier builds ended up in `middleware-manifest.json`. Functions
that changed from edge to server runtime stayed in the manifest as edge
functions.
#### on-demand-entry-handler.ts
When a server or edge entry is added we check if it has switched
runtime. If that's the case the old entry is removed.
#### Reproduce
Create edge API route and visit `/api/hello`
```js
// pages/api/hello.js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server api route and visit `/api/hello`, it will explode.
```js
// pages/api/hello.js
export default function (req, res) {
res.send('Hello')
}
```
#### Bug not fixed
One EDGE case is not fixed. It occurs if you switch between edge and
server runtime several times without changing the content of the file:
Edge runtime
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
Change it to a server runtime
```js
export default function (req, res) {
res.send('Hello')
}
```
Change back to edge runtime, the content of the file is the same as the
first time we compiled the edge runtime version.
```js
export const config = {
runtime: 'experimental-edge',
}
export default () => new Response('Hello')
```
The reason is that both the edge and server compiler emits to the same
file (/.next/server/pages/api/hello.js) which makes this check fail in
webpack:
https://github.com/webpack/webpack/blob/main/lib/Compiler.js#L849-L861
Possible solution is to use different output folders for edge and server

Currently the DEV server can't recover if you export an invalid runtime
config. It ends up in a state where it stops to work but nothing is
printed to the terminal.
It now prints an error but keeps working. When building it should crash,
there's an existing test for that
https://github.com/vercel/next.js/blob/canary/test/production/exported-runtimes-value-validation/index.test.ts#L5-L17
#### Reproduce
```tsx
export default function Page() {
return <p>hello world</p>
}
export const config = {
runtime: 'something-odd',
}
```
## Feature
As the title, support `has` match, `local` that works the same with the `rewrites` and `redirects` of next.config.js on middleware config. With this PR, you can write the config like the following:
```js
export const config = {
matcher: [
"/foo",
{ source: "/bar" },
{
source: "/baz",
has: [
{
type: 'header',
key: 'x-my-header',
value: 'my-value',
}
]
},
{
source: "/en/asdf",
locale: false,
},
]
}
```

- Group edge ssr tests, merge `edge-vs.-non-edge-api-route-priority` and `react-18-streaming-ssr` into 1 e2e test suite
- Add rewrite case to edge ssr in switchable runtime
Currently Edge SSR routes are added to both `routedPages` (catch-all page render routes) and `edgeRoutesSet` (catch-all edge function routes). This causes the request to be handled by both and results in an error (the Node server can't execute the Edge SSR route as a regular page).
Another fix is to make sure Edge Function routes are sorted too, so `/foo` can be caught before dynamic ones like `/[id]`.

x-ref #39199
The change in #39199 isn't correct. Middleware manifest should only contain middleware route, so that when router navigates, it only try to apply middleware instead of checking all edge routes. This PR also changes the middleware manifest global value from array to object for easier access

Fixes#38743.
Fixes: https://github.com/vercel/next.js/pull/38750
The PR adds basic `TemplateLiteral` support for static analysis.
The corresponding re-production of #38743 has also been implemented in e2e tests.
This outputs a separate manifest for leveraging during deploy to handle the new app outputs. Also ensures dynamic routes from `app` our output in the `routes-manifest` correctly along with fixing the `react-dom` import.
