Use CSS Variables for fonts, remove postcss-loader (#13204)

* Use CSS Variables for fonts, remove postcss-loader

- Use CSS variables for fonts, making the fonts easier to customize
- Remove postcss-loader, it's not doing anything useful and is actually
  applying strange transforms on our CSS.

Fixes: https://github.com/go-gitea/gitea/issues/11045

* introduce helper variable, mark documented vars

* work around case issue by always quoting specific fonts

 As of version 1.6.0 Gitea has built-in themes. The two built-in themes are, the default theme `gitea`, and a dark theme `arc-green`. To change the look of your Gitea install change the value of `DEFAULT_THEME` in the [ui](https://docs.gitea.io/en-us/config-cheat-sheet/#ui-ui) section of `app.ini` to another one of the available options.  
 As of version 1.8.0 Gitea also has per-user themes. The list of themes a user can choose from can be configured with the `THEMES` value in the [ui](https://docs.gitea.io/en-us/config-cheat-sheet/#ui-ui) section of `app.ini` (defaults to `gitea` and `arc-green`, light and dark respectively)

+## Customizing fonts

+Fonts can be customized using CSS variables:
+
+```css
+:root {
+  --fonts-proportional: /* custom proportional fonts */ !important;
+  --fonts-monospace: /* custom monospace fonts */ !important;
+  --fonts-emoji: /* custom emoji fonts */ !important;
+}
