Michael Davis f5d95de227 C++: Improve parameter highlighting
This adds parameter highlighting for reference parameters and defaulted
parameters. For example:

```cpp
auto strip_prefix_only(std::string& s,
                       Hidden_Homonym skip_hidden_homonym = {}) const
    -> Affixing_Result<Prefix>;
```

Previously both parameters were only highlighted as variables.
