LOG: [WebAssembly] Clean up CustomMappingTraits<BBNumberMap> (NFC) (#167155)

This patch does two things for readability:

- Use structured bindings.
- Remove extraneous .c_str().

Note that YamlIO.mapRequired takes StringRef as the key type.  As
such, we can implicitly construct StringRef from std::string.

Added: 
    

Modified:

Removed:
