RFR: 8293595: tstrings::any() is missing an overload

[Julian Waters]

tstrings::any() has an overload for std::wstring (if required) but is missing the corresponding operator overload for std::string, leaving only the templated one as a fallback, which will expand into a std::wostringstream << std::string operation. This isn't particularly safe on Windows, considering that JDK-8292008 and JDK-8247283 have been recently merged, and can sporadically cause build failures. This change simply adds the missing overload with the appropriate format handling that jpackage expects from std::string. Also contains minor name changes to fit the rest of the parameter names in the other overloads.
