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):

* Remove customized (unmaintained) dropdown, improve aria a11y for dropdown
* fix repo permission
* use action instead of onChange
* re-order the CSS selector
* fix dropdown behavior for repo permissions, make elements inside menu item non-focusable
* use menu/menuitem instead of combobox/option. use tooltip(data-content) for aria-label, prevent from repeated attaching
* click menu item when pressing Enter
* code format
* fix repo permission
* repo setting: prevent from misleading users when error occurs
* fine tune the repo collaboration access mode dropdown (in case the access mode is undefined in the template)
