Add ARIA support for Fomantic UI checkboxes (#22599)

Replace #22593

This is a general approach to add ARIA support for all Fomantic UI
checkboxes (including radioboxes)

* Pros:
* General approach, it works for all Fomantic UI checkboxes / radioboxes
    * No need to write IDs manually everywhere
    * No need to tell new contributors to write IDs again and again

* Cons:
* Slightly affects performance, but it's really trivial, because there
was already a heavy `$('.ui.checkbox').checkbox()` for Fomantic UI
before. So everything is still fine.

Screenshot (from the repo setting page, which has various checkboxes):
