string_util: remove TString conversion for windows

First of all they are foundamentally broken. As our convention is that std::string is always UTF-8, these functions assume that the multi-byte character version of TString (std::string) from windows is also in UTF-8, which is almost always wrong. We are not going to build multi-byte character build, and even if we do, this dirty work should be handled by frontend framework early.
