fix C++ in-code docs comments to silence warnings

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53775

A refactor to align our C++ code style within `jsinpector-modern`.

We prefer `std::string` and `const std::string&` everywhere (see [C++ Core Guidelines F.15](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rf-conventional)), except for when we are handing potentially very large strings — in which case we must use `string_view` all the way down.
