This will reduce the bundle size and also give user proper hint to upgrade to `head.js`
* Mark `next/head` as noop in app dir
* Add warning for users to check the upgration guide to migrate it to head.js

## Bug
Fixes WEB-166.
This supersedes https://github.com/vercel/next.js/pull/43449, updating
swc_core and turbopack both with its transitive dependencies. Version
bump includes one important build side issues to having circular
dependencies.
This PR fixes two memory leaks I found debugging with @sokra.
## 1) Leak in `next-server.ts`
The first leak was caused by the fact that the `require.cache` associated to the `next-server` module was not being cleared up properly, so we leaked context from modules required in that page, like API routes.
## 2) Leak with React Fetch
When evaluating a route, we also evaluated the `react.shared-subset.development.js` module where React patches the `fetch` function. The problem is that when re-evaluating a route as part of hot reloading, we were patching over the previously patched `fetch` function.
The result of this operation meant that we were keeping a reference to the context of the previous `fetch` and thus to the previous route context, thus creating a memory leak, since we only needed the new context.
## Test plan
Checked manually the heap snapshots of a test app.

As @timneutkens pointed out [here](https://github.com/vercel/next.js/pull/43819#discussion_r1042408158), changing the key will make Flight's module cache grow indefinitely. While I've thought about updating Flight's logic to clean the cache at some point, but that's tricky to do correctly as everything is asynchronous and we have to trigger clean up from outside (Webpack).
So currently, a better way I can think of is to just give Flight a proxied object as `moduleExports`. Even if Flight is getting the same object from cache, it will always require the latest module from Webpack.

Updated version of the reverted https://github.com/vercel/next.js/pull/43511
Unhandled errors that did not occur during React rendering (those errors are caught in `getDerivedStateFromError` in the Error Overlay) should be opened in the minimized toast state instead of fullscreen. For example if they occur in event handlers or setTimeout. Errors that breaks the app, such as uncaught render errors or build errors, still opens up in fullscreen mode.
The added test make sure the errors opens up as minimized, but if there's a breaking error it should "win" and open up in fullscreen. The updated tests either throw errors inside an event handler or a setTimeout, or the error is handled in a custom error boundary - which means the app don't break.
Closes NEXT-128

This is due to new release for the runner image (https://github.com/actions/runner-images/issues/6399) now sets ubuntu 22.04 as latest, but playwright have release to support it (https://github.com/microsoft/playwright/issues/13738) but @replayio/playwright seems not picked it up yet (https://github.com/replayio/replay-cli/blob/main/packages/playwright/package.json#L23)
PR tries to pin to known working image (20.04) until dependencies can support new image gracefully.

### Summary
Migrate `next/dynamic` to implementation based on `React.lazy` and
`Suspense`. Then it becomes easier to migrate the existing code in pages
to layouts. Then we can support both `ssr` and `loading` option for
`next/dynamic`.
For `loading` option, it will work like `Suspense`'s `fallback` property
```js
<Suspense fallback={loading}>
<DynamicComponent />
</Suspense>
```
For `ssr` option, by default `React.lazy` supports SSR, but we'll
disable the `ssr: false` case for dynamic import in server components
since there's no client side involved.
Then we don't need `suspense` option anymore as react >= 18 is always
required. Mark it as deprecated.
It also supports to load client component dynamically in server
components now.
#### Code code changes
* switch loadable component to `lazy` + `Suspense`
* will make sure it's retuning a module from `loader()` to
`loader().then(mod => ({ default: mod.default || mod }))` since `lazy()`
only accepts loader returning a module
* Inside suspense boundary, throwing an error for ssr: false, catch the
error on server and client side and ignore it.
* Ignore options like ssr: false for server components since they're on
server, doesn't make sense
* Remove legacy dynamic related transform
#### Feature changes
* `next/dynamic` will work in the same way across the board (appDir and
pages)
* For the throwing error, will make it become a API that throws error
later in the future, so users can customize more with `Suspense`
* You can load client components now in server components with dynamic.
Resolves#43147
#### Tests
* existing dynamic tests all work
* add case: import client component and load through next/dynamic in
server components
### Issues
This is one of the required changes to refactor bundling strategy for
pages and app.

Previously we were assuming that `serverOnlyChanges` is the same as
"server component changes". However that's not always true, as one can
change a component from server component to client component, or vice
versa, where the change affects both server and client builds, so
`serverOnlyChanges` will be empty.
This PR fixes the logic by strictly hashing and comparing modules in the
server layer. Note that I intentionally skipped the test as this fix
[isn't
complete](https://vercel.slack.com/archives/C035J346QQL/p1670343453333079).
