This PR introduces a more predictable API to manipulate cookies in an Edge Function context.
```js
const response = new NextResponse()
// set a cookie
response.cookies.set('foo, 'bar') // => set-cookie: 'foo=bar; Path=/'`
// set another cookie
response.cookies.set('fooz, 'barz') // => set-cookie: 'foo=bar; Path=/, fooz=barz; Path=/'`
// delete a cookie means mark it as expired
response.cookies.delete('foo') // => set-cookie: 'foo=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT, fooz=barz; Path=/'`
// clear all cookies means mark all of them as expired
response.cookies.clear() // => set-cookie: 'fooz=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT, foo=; Path=/; Expires=Thu, 01 Jan 1970 00:00:00 GMT'`
```
This new cookies API uses [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) interface, and it's available for `NextRequest` and `NextResponse`.
Additionally, you can pass a specific cookies option as a third argument in `set` method:
```js
response.cookies.set('foo', 'bar', {
path: '/',
maxAge: 60 * 60 * 24 * 7,
httpOnly: true,
sameSite: 'strict',
domain: 'example.com'
}
```
**Note**: `maxAge` it's in seconds rather than milliseconds.
Any cookie manipulation will be reflected over the `set-cookie` header, transparently.

Back in 2019, React released the first version of `use-subscription` (https://github.com/facebook/react/pull/15022). At the time, we only has limited information about concurrent rendering, and #9026 add the initial concurrent mode support.
In 2020, React provides a first-party official API `useMutableSource` (https://github.com/reactjs/rfcs/pull/147, https://github.com/facebook/react/pull/18000):
> ... enables React components to safely and efficiently read from a mutable external source in Concurrent Mode.
React 18 introduces `useMutableSource`'s replacement `useSyncExternalStore` (see details here: https://github.com/reactwg/react-18/discussions/86), and React changes `use-subscription` implementation to use `useSyncExternalStore` directly: https://github.com/facebook/react/pull/24289
> In React 18, `React.useSyncExternalStore` is a built-in replacement for `useSubscription`.
>
> This PR makes `useSubscription` simply use `React.useSyncExternalStore` when available. For pre-18, it uses a `use-sync-external-store` shim which is very similar in `use-subscription` but fixes some flaws with concurrent rendering.
And according to `use-subscription`:
> You may now migrate to [`use-sync-external-store`](https://www.npmjs.com/package/use-sync-external-store) directly instead, which has the same API as `React.useSyncExternalStore`. The `use-subscription` package is now a thin wrapper over `use-sync-external-store` and will not be updated further.
The PR does exactly that:
- Removes the precompiled `use-subscription` introduced in #35746
- Adds the `use-sync-external-store` to the dependencies.
- The `use-sync-external-store` package enables compatibility with React 16 and React 17.
- Do not pre-compile `use-sync-external-store` since it is also the dependency of some popular React state management libraries like `react-redux`, `zustand`, `valtio`, `@xstate/react` and `@apollo/client`, etc. By install
- Replace `useSubscription` usage with `useSyncExternalStore`

`preact/compat` doesn't have `/server.browser` exports, to make it work with latest of next.js:
* use `react-dom/server` to detect if it could opt-in streaming rendering by checking react 18 `renderToPipeableStream` API in short time fix. In long term `preact/compat`should support `/server.browser` that same with react 17.
* Also filed a PR to `next-plugin-preact` to skip chunk-prepending to pages in edge compiler

## Description
This PR implements a new configuration object in `next.config.js` called `experimental.images.remotePatterns`.
This will eventually deprecate `images.domains` because it covers the same use cases and more by allowing wildcard pattern matching on `hostname` and `pathname` and also allows restricting `protocol` and `port`.

## Documentation
There are three Trusted Types violations that are fixed in this PR:
### 1. ban-element-innerhtml-assignments: maintain--tab-focus.ts
The innerHTML assignment here is unsafe as a string is being used that could contain an XSS attack. The solution chosen was to replace the string containing HTML with programmatically-created DOM elements. This removes the Trusted Types violation as there is no longer a string passed in that can contain an XSS attack.
Notes on solution:
- The `<svg>` tag is omitted completely since the original snippet returns fragment.firstChild.firstChild. The first firstChild omits the `<div>`, and the second firstChild omits the `<svg>`, so to remove unnecessary code the created elements start at the foreignObject level.
- The reason createElementNS is used instead of createElement is because the ‘foreignObject’ element is a separate namespace from the default HTML elements. The documentation for this command is found [here](https://developer.mozilla.org/en-US/docs/Web/API/Document/createElementNS).
The code was tested to be equivalent by rendering both the original code and the re-written code in a browser to see if they evaluate to the same thing in the DOM. The DOM elements styles were then compared to ensure that they were identical.
### 2. ban-window-stringfunctiondef: packages/next/lib/recursive-delete.ts
The setTimeout function caused a Trusted Types violation because if a string is passed in as the callback, XSS can occur. The solution to this problem is to ensure that only function callbacks can be passed to setTimeout. There is only one call to the sleep function and it does not involve a string callback, so this can be enforced without breaking the application logic. In the process of doing this, promisify has been removed and the promise has been created explicitly.
The code was tested in a sample application to ensure it behaved as expected.
### 3. ban-window-stringfunctiondef: packages/next/client/dev/fouc.ts
This file also uses setTimeout, so the call was wrapped in a `safeSetTimeout` call that specifies that the callback argument is not a string.
This variable is exported by next but undocumented, and its usage is necessary to build auxiliary scripts for your server-side applications. See https://github.com/vercel/next.js/issues/36237#issuecomment-1117694528 for an example.

## Documentation
There is one tsec violation that is fixed in this PR:
### 1. ban-script-src-assignment: route-loader.ts
XSS can occur with the line script.src = src in appendScript(src, script) if src can be controlled by a malicious user. From tracing through the code, it was determined that src comes from the function `getFilesForRoute(route)`. The behaviour of this function differs depending on the environment (development vs. production), but in both cases the function will construct strings that lead to valid file paths. These strings depend on two variables: `assetPrefix` and `route`, but due to the nature of the constructed strings it was determined that the scripts here are safe to use. Thus, the solution was to promote these strings to `TrustedScriptURL`s. This is the Trusted Types way of declaring that the script URL passed to the DOM sink is safe from DOM XSS attacks.
To create a `TrustedScriptURL`, a policy needs to be created. This policy was put in its own file: `client/trusted-types.ts`. This policy has the name `nextjs`. If this name should be changed to something else, feel free to change it now. However, once it is released to the public and application developers begin using it, it may be harder to change the value since any application developers with a custom policy name allowlist would now need to update their `next.config.js` headers to allow this new name.
The code was tested in a sample application to ensure it behaved as expected.

* Added type to Page Component for TypeScript
Following this tutorial, I noticed that TS was complaining that "getLayout" did not exist on Page. That is normal since Page is typed as NextPage. I simply exported the new type we create in "_App.tsx" and used it as the return type for Page. This will probably help others seeing that red in their editors and perhaps being confused.
* Small linting change
* Apply suggestions from code review
* Update layouts.md
* lint fix
* update type

Follow-up to https://github.com/vercel/next.js/pull/36527 this adds falling back to the wasm swc build when loading the native bindings fails so that we don't block the build on the native dependency being available.
This continues off of https://github.com/vercel/next.js/pull/33496 but does not add a postinstall script yet and only downloads the fallback when the native dependency fails to load.
