Removes several styles that were used for
expanding/collapsing the table of contents at narrow
widths for non-js users as well as the main menu
for no-js users.
Existing `.vector-menu-checkbox` styles address this
use-case with the addition of a display:none rule for the
two affected checkboxes.
Related to the Page Tools clean-up since these styles
were once scoped to the .vector-page-tools-disabled
class.

- Fixes TOC button being transparent (https://jmp.sh/jbuivqlM). FYI the fixed width toggle button has the same issue.
- Add replace `html-vector-heading-icon` with Icon.mustache
