Upload 组件中的showUploadList是否可以添加点击选中事件的功能

[fatetoper]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

点击showUploadList的图片可以选中（添加个边框颜色），再次点击选中取消选中。点击同时触发点击事件，把选中的item数据对象传到外部。

What does the proposed API look like?

@select="handleSelect"

添加 itemRender 来自定义列表更加通用
