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.
