BREAKING CHANGE: This rewrite some styles to leverage Tailwind's
`@apply` directive in stead of SASS mixins' `@include`.

Consuming GitLab UI's stylesheets from the source therefore requires
Tailwind to be set up on the consumer's end to properly compile those
directives. An alternative is to consume the compiled CSS bundles.

A single `@apply` directive can apply several utils at once.
