[swc-plugin-angular] Functional APIs (e.g. input()) are broken if a property is declared in the constructor

[yjaaidi]

This doesn't work because the input is not decorated:

class MyCmp {
  title = input();
  constructor(private myService: MyService) {}
}

This happens because this is parsed by SWC as:

class MyCmp {
  title;
  private myService;
  constructor(myService) {
    this.myService = myService;
    this.title = input();
  }
}

We have to detect functional APIs in the constructor.

Meanwhile, the workaround is to use the inject() function which is the approach I'd recommend in general.
