BREAKING CHANGE: Drop support for React 17 and earlier
Support for React 17 an earlier is provided by
`@playwright/experimental-ct-react-17`
Closes#19923
The actual API of the object is not implemented because those who want
to test it will likely need their own mock and for the browser detection
logic (as described in the bug) just having the property on window
should be sufficient.
Fixes#21037
This enables `allowDeclareFields` flag that allows code like:
```ts
class Foo {
declare prop: string;
}
```
Declaring is a workaround for inheritance vs property initialization
issues.
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#the-usedefineforclassfields-flag-and-the-declare-property-modifier
For `allowDeclareFields` to work, we have to run
plugin-transform-typescript before plugin-proposal-class-properties and
few others, so this change migrates from preset-typescript that always
runs last to individual plugin-transform-typescript, and reorders some
plugins.
References #21119.
For all custom elements defined in the page, we preserve their names and
define them in the rendered snapshot.
This makes things like `:defined` css pseudo work.
Fixes#21030.
It turns out these new contextmenu-based tests do not work on
Chromium-based browsers on Windows.
We consider context menu support a best-effort, so we skip them
for now.
There is currently a bug when running `node@18.14.2` when running with
experimentalLoader
```
TypeError: The URL must be of scheme file
at new NodeError (node:internal/errors:399:5)
at Object.fileURLToPath (node:internal/url:1492:11)
at resolve (./node_modules/@playwright/test/lib/experimentalLoader.js:39:48)

at ESMLoader.getModuleJob (node:internal/modules/esm/loader:424:7)
at ModuleWrap.<anonymous> (node:internal/modules/esm/module_job:79:21)
```
This came from my test `vrt.spec.ts` which had a non package import
inside of it
```ts
import fs from "node:fs/promises"
```
The test run failed due to node imports not returning fileUrls when
resolved.

Not sure whats actually going on here, turns out this breaks the trace
viewer on firefox. -> all the iframes won't work.
Can't repro on stock firefox, so seems like something fishy on our end.
