								Improve `<SvgIcon>` to make it output `svg` node and optimize performance (#23570)
							
							
							
							
							
							
							
							Before, the Vue `<SvgIcon>` always outputs DOM nodes like: 
```html
<span class="outer-class">
    <svg class="class-name-defined" ...></svg>
</span>
```
The `span` is redundant and I guess such layout and the inconsistent
`class/class-name` attributes would cause bugs sooner or later.
This PR makes the `<SvgIcon>` clear, and it's faster than before,
because it doesn't need to parse the whole SVG string.
