Subject: [PATCH] Adwaita: Fix link styling

- Fix broken visited link styling by avoiding invalid selector
  `:link:visited` - CSS :link and :visited are mutually exclusive.
- In link button, move %link from the child label to the parent button,
  so that the hover/active effect is applied within the whole button and
  the visited style is applied correctly.
- Remove invalid selectors `:backdrop:backdrop`.
