I was looking into simplifying our scrollbar styles: * StyleAppearance::Resizer is not used in content, and some of the values were only for <xul:window> which are not supported anymore. * Statusbarpanel and Resizerpanel aren't used. Statusbar is only used once on macOS so we only need to keep it there. Differential Revision: https://phabricator.services.mozilla.com/D178374
