David Farler e87be804c9 [Markup] Slurp fenced code block info string ...

Add a language property for Markup code blocks - the default is
"swift" but will respect overrides such as the following:

```c++
Something::Somethign::create()
```

For code listings in doc comments written in other languages, such
as when you want to compare usage against another language.
