std::stop_token& operator=( const std::stop_token& other ) noexcept;	(1)	(C++20 起)
std::stop_token& operator=( std::stop_token&& other ) noexcept;	(2)	(C++20 起)

以 other 的关联停止状态替换关联停止状态。

1) 复制赋值 other 的关联停止状态给 *this 的。等价于 stop_token(other).swap(*this) 。

2) 移动赋值 other 的关联停止状态给 *this 的。赋值后 *this 含有先前 other 的关联停止状态，而 other 无关联停止状态。等价于 stop_token(std::move(other)).swap(*this) 。
