Generate swagger definitions for Fields<T>

We noticed there was no OAS definitions for Fields (e.g. Field for a simple case).

class UserDto : public oatpp::DTO {
  // [...]
  DTO_FIELD(Fields<String>, todoList);
  DTO_FIELD(Fields<Fields<String>>, todoTree);
  DTO_FIELD(Fields<Int64>, numberList);
  DTO_FIELD(Fields<Object<UserDto>>, friendsByNickname);
  DTO_FIELD(Fields<List<String>>, taskForFriends);
  // [...]
};

To generate something like:

{
  // [...]
  "todoList": {
    "type": "object",
    "additionalProperties": {
      "type": "string"
    }
  },
  "numberList": {
    "type": "object",
    "additionalProperties": {
      "type": "integer",
      "format": "int64"
    }
  },
  "friendsByNickname": {
    "type": "object",
    "additionalProperties": {
      "$ref": "#\/components\/schemas\/UserDto"
    }
  },
  "taskForFriends": {
    "type": "object",
    "additionalProperties": {
      "type": "array",
      "items": {
        "type": "string"
      }
    }
  },
  "todoTree": {
    "type": "object",
    "additionalProperties": {
      "type": "object",
      "additionalProperties": {
        "type": "string"
      }
    }
  }
  // [...]
}
