Use tippy.js for context popup (#20393)

By appending the tooltips to `document.body`, we can avoid any stacking context issues caused by surrounding element's CSS.

This uses [tippy.js](https://github.com/atomiks/tippyjs) instead of Fomantic popups. We should aim to replace all Fomantic popups with this eventually and then get rid of the Fomantic `popup` module completely.
