test: add tests for console.[info|error|warn]
Just copied the basic tests for log, as they're all the same thing as log in either stdout or stderr. Cleaned that up a bit. Also const-ified. PR-URL: #6538 Reviewed-By: Colin Ihrig <cjihrig@gmail.com> Reviewed-By: Evan Lucas <evanlucas@me.com> Reviewed-By: James M Snell <jasnell@gmail.com>
