HarmonyOS 鸿蒙Next ArkTS实现深拷贝方法，禁用any和对象操作

function deepCopy(obj: any): any {
  if (typeof obj !== "object" || obj === null) {
    return obj;
  }
  let copy: any;
  if (Array.isArray(obj)) {
    copy = [];
    for (let i = 0; i < obj.length; i++) {
      copy[i] = deepCopy(obj[i]);
    }
  } else {
    copy = {};
    for (let key in obj) {
      if (obj.hasOwnProperty(key)) {
        copy[key] = deepCopy(obj[key]);
      }
    }
  }
  return copy;
}

any可以用ESObject代替
