Hope that Spin will provide the way to use the service #4312
Description
- I have searched the issues of this repository and believe that this is not a duplicate.
What problem does this feature solve?
如果提供服务的方式，可以更加方便的使用 hook 的方式使用加载效果。相同的功能在 element-plus 中有服务功能，https://element-plus.gitee.io/#/zh-CN/component/loading#fu-wu。
What does the proposed API look like?
Spin.service({
target: HtmlElement,
text: string,
background: string,
...
});
