DEV: makes discourse-styleguide core (styleguide) (#10847)

This plugin is only useful for developers, however, making it core allows us to centralize any component modification in one commit.

This integration also adds a new site_setting: `styleguide_admin_only` which allows to enable a styleguide on a live site while restricting visibility to admins only.

By default, styleguide is disabled.

+    If you want to scale the fonts of a specific element, you can use Discourse's font scaling variables. Using the variable system ensures you're using a consistent set of font-sizes throughout your community.
+    <p>
+      Changing the font-size of a parent element will proportionately scale the font sizes of all its children.
+    </p>
+    <pre>
+      .parent {
+        <span class="hljs-attribute">font-size</span>: $font-up-3;
+        <span>// Increases the relative font-size of this element and its children by 3 steps in the scale</span>
+        .child {
+          <span>// If this is set to $font-down-3 in Discourse's default CSS,
+             the parent font-size increase above would make this equivilant to $font-0
+             ($font-down-3 + $font-up-3 = $font-0)</span>
+        }
+      }
