Display sidebar on no-TOC pages

[zenoachtig]

This PR changes the display behaviour of the left sidebar on pages that are configured to not show the table of contents.

This behaviour mirrors the right sidebar, which displays the mode toggle even if the page's outline option is set to hidden. When no-toc is enabled on a page, the table of contents is hidden from the sidebar. Any other elements, like the variant selector, logo, search bar and GitBook trademark, are still shown. On no-toc pages the sidebar shrinks in width to match the right sidebar, ensuring the same centred layout that no-toc pages currently feature.

On no-toc pages, the variant selector was previously shown in the header. Together with this change, the variant selector on no-toc pages now moves to the same secondary bar used for sections (if there are sections it is shown next to them, if there are no sections it is the only element in this bar). Together, these changes allow for better and more consistent landing pages.
