Specialize OsString::push for strings
When concatenating two WTF-8 strings, surrogate pairs at the boundaries need to be joined. However, since UTF-8 strings cannot contain surrogate halves, this check can be skipped when one string is UTF-8. Specialize `OsString::push` to use a more efficient concatenation in this case. Unfortunately, a specialization for `T: AsRef<str>` conflicts with `T: AsRef<OsStr>`, so stamp out string types with a macro.
