Notification能否有堆叠的效果，antd有堆叠的模式，stack #7868
Description
- I have searched the issues of this repository and believe that this is not a duplicate.
What problem does this feature solve?
堆叠模式，超过阈值时会将所有消息收起
What does the proposed API look like?
const openNotification = () => {
notification.open({
message: 'Notification Title',
stack: true,
threshold: 3,
description:
'This is the content of the notification.',
});
};
