Fine tune more downdrop settings, use SVG for labels, improve Repo Topic Edit form (#23626)
Although it seems that some different purposes are mixed in this PR,
however, they are all related, and can be tested together, so I put them
together to save everyone's time.

Diff: `+79 −84`, everything becomes much better.

### Improve the dropdown settings.

Move all fomantic-init related code into our `fomantic.js`

Fine-tune some dropdown global settings, see the comments.

Also help to fix the first problem in #23625 , cc: @yp05327 

The "language" menu has been simplified, and it works with small-height
window better.

### Use SVG instead of `<i class="delete icon">`

It's also done by `$.fn.dropdown.settings.templates.label` , cc:
@silverwind

### Remove incorrect `tabable` CSS class

It doesn't have CSS styles, and it was only in Vue. So it's totally
unnecessary, remove it by the way.

### Improve the Repo Topic Edit form

* Simplify the code
* Add a "Cancel" button
* Align elements
