Move some JS code from fomantic.js to standalone files (#27994)
To improve maintainability, this PR: 1. Rename `web_src/js/modules/aria` to `web_src/js/modules/fomantic` (the code there are all for aria of fomantic) 2. Move api/transition related code to `web_src/js/modules/fomantic/api.js` and `web_src/js/modules/fomantic/transition.js` No logic is changed.
