HarmonyOS 鸿蒙Next可以重载构造函数吗

ArkTS的方法名只能有一个，可以用 `?` 或 `|` 来模拟java中的重载

参考：[https://developer.huawei.com/consumer/cn/blog/topic/03155928036735011](https://developer.huawei.com/consumer/cn/blog/topic/03155928036735011)

```javascript
export class BaseKeyValueBean {
  key?: string;
  value?: string;
  hasClick?: boolean;
  textColor?: ResourceColor;

  // 第一个构造函数签名
  constructor(key: string, value: string);

  // 第二个构造函数签名
  constructor(key: string, value: string, hasClick: boolean, textColor: ResourceColor);

  // 构造函数体，根据参数数量决定如何初始化
  constructor(key: string, value: string, hasClick?: boolean, textColor?: ResourceColor) {
    this.key = key;
    this.value = value;
    if (hasClick !== undefined) {
      this.hasClick = hasClick;
    }
    if (textColor !== undefined) {
      this.textColor = textColor;
    }
  }
}
