FR: Add autocompletion in setAttributes() for Model successors

[wapmorgan]

It would be nice if autocompletion work for Model::setAttributes($values) just like for BaseObject::__construct($config = []) (with Go To, Rename and etc).

What steps will reproduce the problem?

Have a model

class User extends Model {
  public $name;
}

Set attributes of model:

$model = new User();
$model->setAttributes([
  'name' => $name,
], false);

What is the expected result?

Working Go-To for name assignment.

What do you get instead?

Cannot find declaration to go to.
