### Changes
#### Feature
* Adopt `React.lazy` into `next/dynamic`, enable it when `options.suspense` is `true`
* Support `next/dynamic` with `suspense=true` in SSR and SSG
#### Tests
| Scenario | Case | Behavior |
|:----:|:----:|:----:|
| basics | react 17 or 18 by default | dev/build error or pass |
| blocking rendering | `reactRoot: true` + `concurrentFeatures: false` | dev/build pass |
| concurrent rendering | `reactRoot: true` + `concurrentFeatures: true` | dev/build pass |

Remove unnecessary `React.Suspense` checks, as the minimum supported version is `react@>=17.0.1`. Also removes some files from the `react-18` integration test that are no longer necessary as of #26664.
I recently received the "Props must be returned as a plain object" error when I accidentally dropped an array directly inside `props`. This is a trivial error to fix once you know what you did, but I spent good 30 minutes looking in all the wrong places. I hope that this slight clarification in the error message would save someone from wasting their time if they make a similar mistake like myself.
Fixes#19862
Avoid executing `webpack` property on `loadableGenerated` of loadable component compiled from `next/dynamic` when `require.resolveWeak` is unavailable due to jest runtime missing `require.resolveWeak`.
## Bug
- [x] Related issues linked using `fixes #number`
- [x] unit tests added
The current `<Image />` component does not fallback gracefully when JavaScript is disabled in the client / browser.
You can test this with the [official Next/Image example](https://csb-4k0kr-p8ya8f304.vercel.app/), by disabling JavaScript in the browser's DevTools. Video demo: https://streamable.com/frkvw9
This PR aims to fix this behaviour by using `<noscript></noscript>` tags to conditionally display a standard `<img>` element using the `props` passed to `<Image />` when JavaScript is disabled.
For browser sessions where JavaScript is enabled, this will not cause an increase in network requests, so there should be no downside.
One area where this PR is a bit "hacky" is that it uses a negative `margin-top` to counteract `sizerStyle.paddingTop`. From what I can tell, `sizerStyle.paddingTop` is generated on the server side, where we can not know ahead of time whether JavaScript is enabled in the browser - hence why I've opted for this solution.

I tried the preset provided at `packages/next-plugin-storybook` but it was raising error due to an [unsafe negation](https://eslint.org/docs/rules/no-unsafe-negation) in the `preset.js` file.
I added a test to show the error:
```
● next-plugin-storybook filterModuleRules › should filter module rules correctly
TypeError: rule.test.test is not a function
48 | if (!rule.test instanceof RegExp) return true
49 | // use Next.js' built-in CSS
> 50 | if (rule.test.test('hello.css')) {
| ^
51 | return false
52 | }
53 | // use next-babel-loader instead of storybook's babel-loader

```
This PR fixes a bug where `next/babel` would accidentally enable development transforms for a production build (`next build`).
This is tested by the two updated unit tests (which removed a workaround for this bug, and one now properly enables dev transforms).

Fixes#18929Fixes#19001
x-ref #19046
x-ref #17032
This reverts #18921 and ensures that the Babel runtime is only inlined as an absolute path when using PnP as before, but then including the correction this resolution as implemented by @merceyz only in the PnP cases, while keeping the diff to a minimum.
This PR removes the modern mode experiment because:
- It does not yield meaningful bundle size wins when compared to other initiatives we've taken
- It's not compatible with webpack 5 (which we're upgrading to)
- It's currently broken and causes most apps to malfunction
- There's no champion currently owning the experiment
We can re-introduce this in the future when we'd like to make it a default for all Next.js apps.
Note: **Next.js still supports Differential Loading (`nomodule`) and does it by default.** This PR strictly removes the experimental modern _syntax_, and does not disable our existing modern/legacy polyfilling.

This replaces the seen set with a newly instantiated map of refs per
value in the array. This corrects the behavior that the refs map passed
into isSerializable contains only values along the path to the current
value: previously, because the refs map was shared among all values in
the array, this would trigger on instances such as:
```js
const x = [];
isSerializableProps('/', 'test', { arr: [x, [x]] });
```
... where the reference is shared but there is no cycle formed, as the
presence of elements is disjoint.
Fixes#18228.
Next.js plugins like `@next/mdx` inject additional webpack loaders to compile files, but they omit the necessary loader for Fast Refresh to work.
Instead of making these files deopt out of Fast Refresh, we can automatically detect and inject the loader in these cases.
Fixes#13574
This updates the named regexes output in the `routes-manifest` and the associated `routeKeys` to not use any non-word characters as this breaks the named regexes e.g. `"Invalid regular expression: "^/(?<data\-provider\-id>[^/]+?)(?:/)?$"`

This pull request refactors our TypeScript preflight check in preparation for dropping the `fork-ts-checker-webpack-plugin` plugin.
This will make reviewing the subsequent PR much easier.

There is no behavior change, so the existing test should cover this adequately.
* Allow `@babel/preset-typescript` to be configured
Some usages, e.g. [getting parameter decorators to work properly](https://github.com/WarnerHooh/babel-plugin-parameter-decorator/pull/19), require configuring `@babel/preset-typescript`.
This commit adds that functionality to `next/babel`.
