Tooltip组件增加自动关闭功能

What problem does this feature solve?

Tooltip一直显示没有自动关闭功能，如果这时用了Popconfirm或其它组件弹出的提示会被遮挡（因为鼠标并没有移动），我想如果有一个自动关闭功能可以缓解此问题，或者能实现点击就自动关闭可以完全解决该问题

What does the proposed API look like?

增加一个autoClose属性，number类型，默认值0，表示不自动关闭，设置了n数值就延迟n毫秒关闭
还可以直接增加一个clickClose属性，boolean类型，默认值false，为true时，鼠标点击关闭
可以参考: https://element-plus.gitee.io/zh-CN/component/popover.html#attributes
