Large specifications with many (nested) sections are painful to navigate through when the TOC is expanded by default. Introduce four new options, "Expand/Collapse whole section" is based on Kate's document view while "Expand/Collapse all" was added to handle the top-level sections. As for other viewers, PDF.js uses shift-click to handle the former while using double-click on a the TOC icon to handle the latter. That is not very obvious, so extending the context menu seems the next best option. BUG: 216870 Differential Revision: https://phabricator.kde.org/D14904
