Replace Less with CSS (#23481)

Ran most of the Less files through the Less compiler and Prettier and
then followed up with a round of manual fixes.

The Less compiler had unfortunately stripped all `//` style comments
that I had to restore (It did preserve `/* */` comments). Other fixes
include duplicate selector removal which were revealed after the
transpilation and which weren't caught by stylelint before but now are.

-gt-hidden must be placed after all other "display: xxx !important" classes to win the chance
-do not use:
-* "[hidden]" attribute: it's too weak, can not be applied to an element with "display: flex"
-* ".hidden" class: it has been polluted by Fomantic UI in many cases
-* inline style="display: none": it's difficult to tweak
-* jQuery's show/hide/toggle: it can not show/hide elements with "display: xxx !important"
-only use:
-* this ".gt-hidden" class
-* showElem/hideElem/toggleElem functions in "utils/dom.js"
