* ESNext+[[Define]]: reference to param props illegal
When target: "esnext" and useDefineForClassFields: true, property
declaration initialisers should not be able to reference parameter
properties; class fields are initialised before the constructor runs,
but parameter properties are not:
```ts
class C {
foo = this.bar
constructor(public bar: string) { }
}
```
emits code that looks like this:
```js
class C {
bar
foo = this.bar
constructor(bar) {
this.bar = bar
}
}
new C('x').foo.length // crashes; foo is undefined
```
This PR adds an error on foo's declaration with ESNext+[[Define]].
* improve test
