[CS2] Literate CoffeeScript without dependencies (#4509)

Browse source 
* Reimplement `invertLiterate` without any dependency, tracking indentation levels (including inside lists); update literate test files to also check that no tests are skipped

* Drop Literate CoffeeScript’s support for executable code blocks inside list items (and also for second paragraphs or blockquotes in list items)

* Update Literate CoffeeScript docs to reflect current supported syntax
