Hi,
- Remove inlined CSS style which have minor performance loss. And hoist it to top of the component.
> Each time you inline an object, React re-creates a new reference to this object on every render. This causes components that receive this object to treat it as a referentially different one which have some performance pitfalls.
_Extremely sorry if I made any mistakes :(_

This PR removes the default styling of `object-fit:"contain"` for images using the future image component. This means images will get the default `object-fit` behavior of `"fill"`.
The main reason for this change is that an inline style will take precedence over external CSS, making this default behavior difficult to override with some styling strategies.

Currently next.js polyfills a [subset](https://github.com/vercel/next.js/blob/canary/packages/next-polyfill-nomodule/src/index.js) of APIs for `nomodule` browsers (such as IE 11), however it's not immediately clear to developers which APIs are transparently polyfilled.
For example, currently `Object.entries` is polyfilled and thus is usable in IE 11, but [it was decided](https://github.com/vercel/next.js/pull/15772#discussion_r463984612) that `Object.fromEntries` should not be polyfilled. As a developer, this is a confusing situation until you end up finding the `next-polyfill-nomodule` list of polyfills that are included.
This PR attempts to improve the Supported Browser Features page by:
- linking to the list of polyfills
- clarifying that custom polyfills are required for IE11 (and other old browser) compatibility
- moving the section on Sever-Side polyfills further down the page so all browser polyfill sections are better grouped together

Use flush effects to custom apply css-in-js solution to app. Re-introduce flush effects to app-render, and remove default support of styled-jsx in `app/`. So that users will choose their own css-in-js solution if they need any customization. styled-jsx won't appear in client bundle if you didn't use it.
For now we have to inject the initial styles before `</head>` to avoid hydration errors. Later on we can remove this once react can handle it.
- [x] inject styles before end of head element
- [x] add tests

This PR specifically calls out in more clear language how the rewrites function behaves. This tripped me up recently as I recently came looking for more information, and the documentation left me with more questions than answers. This is an attempt to clear up the confusion I walked away with for anyone who comes in after me.

This commit allows the users to import URLPattern from `next/server`,
by defining a key that uses `global.URLPattern`.
Why is this any good? or: why don't we add URLPattern to the global namespace?
URLPattern is exposed as global on Edge Runtime _only_. This means that if we define a
constructor in global namespace in our TypeScript definitions, people might
have runtime errors in their Node.js functions.
Importing from `next/server` enables users to get the constructor without
risking in runtime errors and wrong type definitions.
Keep in mind, that with the current implementation, we do not check if the
constructor actually exists, but `next/server` shouldn't be imported in
Node.js functions, AFAIK.

This ensures we properly leverage the `assetPrefix` for `app`. Note for reviewing the test changes are mostly spacing so hiding that may help.

Fixes: [slack thread](https://vercel.slack.com/archives/C035J346QQL/p1659387244559979)
This PR fixes an issue where tests fail because the generated tmp directory already exists. This is likely caused from two tmp dirs being generated in the same millisecond.
```
Failed to create next instance [Error: EEXIST: file already exists, mkdir '/tmp/next-repo-1659368089063/packages'] {
errno: -17,

This PR adds a `fill` attribute to the future image component, that behave similarly to the fill mode on the existing image component.
Functionally, it mainly adds `position: "absolute"` and `object-fit: "contain"` to the image element, along with `height: "100%"` and `width: "100%"` to preserve the image aspect ratio. All of these can be overwritten by the user, except for `position: "absolute"`, which will throw an error. This is because changing that property without height and width is likely to cause layout shift.
Because we no longer have the wrapper element, this new version of `fill` requires that the user set `overflow: "hidden"` on the parent element themself, if they want that behavior.
This PR also includes several runtime checks to catch instances where the fill mode may provide unexpected results. These runtime checks warn if:
* The image doesn't have the `sizes` attribute and loads much smaller than the viewport
* The containing element does not have `position: "relative"`
* The image height value is 0

When we detect if `reactRoot` rendering should be enabled we `require` the require to check the version. But at that time the `NODE_ENV` isn't set yet. Then the react dev build stays in the `require.cache` that any future require of react will get the wrong build. In that case, React dev bundle is picked in production mode.
Fun fact: if you're using hooks, that seem not to effect you, but context consumer works different then you couldn't get the proper context from provider.

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

In `Generating paths on-demand` section
It was mentioned that `getStaticProps` allows you to control which pages are generated during the build.
But `getStaticPaths` will allows us to control which pages are generated during the build.

P.S.: local copy fails `pnpm lint` due to the `target` subfolder with intermediate rust build artifacts... should I add a `.prettierignore` update to exclude `/packages/next-swc/target/`?

Previous next versions supported nested version of middleware, now we simplify it to one global middleware. This PR clarify the middleware and edge functions usage in dev server
Add `next/dist/client/components/shared/dynamic` as shared api which server and client components can both support.
Dynamic imports will be part of flight on server side.
This pr doesn't contain preloading part for client components.
