 Twenty Twenty-One: Remove duplicate CSS rules.

 Introduces a new PostCSS plugin, `postcss-discard-duplicates`, which will
 automatically remove any duplicate CSS rules. All the CSS that is removed
 shows up again later in the file. This also fixes a bug from `postcss-css-
 variables`, where media queries are duplicated.

 Fixes #52158.
 Props poena.
