overlookmotel e76fbb0721 fix(transformer/class-properties): fix symbol clashes in instance prop initializers (#7872) 
Instance property initializers are moved into constructor. If symbols they reference are shadowed within constructor, rename those symbols.

Input:

```js
class C {
  prop = foo();
  constructor(foo) {
    console.log(foo);
  }
}
```

Output:

```js
class C {
  constructor(_foo) { // <-- renamed
    this.prop = foo(); // <-- moved into constructor
    console.log(_foo); // <-- renamed
  }
}
```
