fix: prevent transpilation issues by using this to reference static…

… props (#11088)

**Related Issue:** #10731

## Summary

Referencing the class would cause incorrect JS output in certain vite
builds:

**source ✅**
```ts
class i {
  static {
    this.DECIMALS = 100;
  }
  static {
    this.SHIFT = BigInt("1" + "0".repeat(i.DECIMALS));
  }
}
```

**transpiled ❌**

```ts
var b = class {
  static{this.DECIMALS = 100;}
  static{this.SHIFT = BigInt("1" + "0".repeat(b.DECIMALS));} // TypeError: Cannot read properties of undefined (reading 'DECIMALS')
}
```
