[Feature Request] image-viewer

### Existing Component
是

### Component Name
Image

### Description
When using the Image component, the source code for the Image component depends on the image-viewer, but the Image viewer is not exposed. There are some scenarios during development: In a table, click on the text in the action column to see the picture corresponding to the current data. Existing images are not suitable for this scenario. I recommend exposing the image-viewer component or adding a copywriting slot to the Image component.（ 在使用Image组件的时候，发现源码中Image组件依赖于image-viewer，可是这个图片查看器却没有向外暴露出来。在开发过程中有一些场景：在表格中，点击操作列的文字，查看当前数据对应的图片。现有的Image是无法满足这种场景的，我建议把image-viewer组件暴露出来，或者Image组件增加文案插槽。）
