…ializer (oxc-project#12848)

For the record, here's the whole process:

[TypeScript ES2022 + useDefineForClassFields = false](https://www.typescriptlang.org/play/?useDefineForClassFields=true&noUnusedLocals=true&noUnusedParameters=true&experimentalDecorators=true&emitDecoratorMetadata=true&target=9&jsx=0&module=0&stripInternal=false&isolatedModules=false&verbatimModuleSyntax=false&allowSyntheticDefaultImports=true&isolatedDeclarations=false&noCheck=false&lib=true&ts=5.9.2&filetype=ts#code/MYGwhgzhAEDC0G8BQ1oQC5nQS2NAZtALyIC+A3EqUA) transforms

(Note Oxc has the exact same transform)

```js
class C {
  static f = side_effect();
}
```

into

```js
class C {
  static {
    this.f = side_effect();
  }
}
```

then babel [@babel/plugin-transform-class-static-block](https://babel.dev/repl#?corejs=3.21&spec=true&code_lz=MYGwhgzhAEDC0G8BQ1XQgFzBglsR0GAFjhAHQBm0AvIgL4Dc0dSdQA&forceAllTransforms=true&modules=commonjs&timeTravel=true&sourceType=module&lineWrap=true&presets=react%2Ctypescript&version=7.26.1&externalPlugins=%40babel%2Fplugin-transform-class-static-block%407.27.1) transforms to

(Note Oxc has the exact same transform)

```js
class C {
  static #_ = this.f = side_effect();
}
```

and the minifier remove unused code trims it down to

```js
this.f = side_effect();
```

---

To eliminate this bug, we will temporary keep all classes that have static properties + side effect initializer.

i.e.

```js
class C {
  static #_ = this.f = side_effect();
}
```

does not get trimmed down to `this.f = side_effect()`.

---

Also note, this came from a project with a tsconfig

```js
"useDefineForClassFields": false
```

+ browserslist target `ios 16` where ES2022 `@babel/plugin-transform-class-properties` is off and ES2022 `@babel/plugin-transform-class-static-block` on.
