检查当前的 `std::future` 对象是否有效，即释放与某个共享状态相关联。

一个有效的 `std::future` 对象只能通过 `std::async()`, `std::future::get_future` 或者 `std::packaged_task::get_future` 来初始化。
一个有效的 `std::future` 对象只能通过 `std::async()`, `std::promise::get_future` 或者 `std::packaged_task::get_future` 来初始化。

另外由 `std::future` 默认构造函数创建的 `std::future` 对象是无效(`invalid`)的，当然通过 `std::future` 的 `move` 赋值后该 `std::future` 对象也可以变为 `valid`。
