As promised in #2970, this attempts to migrate code to a common set of utilities in a common place in the code and use them everywhere. This also exports the functionality, since the Windows API with WideCharToMultiByte is fairly verbose relative to what libuv and libuv's clients typically need, so it is useful not to require clients to reimplement this conversion logic unnecessarily (and because Windows is not 64-bit ready here, but this implementation is.)
