This PR upstreams the Verso parser and adds preliminary support for Verso in docstrings. This will allow the compiler to check examples and cross-references in documentation. After a `stage0` update, a follow-up PR will add the appropriate attributes that allow the feature to be used. The parser tests from Verso also remain to be upstreamed, and user-facing documentation will be added once the feature has been used on more internals.
