[Support] Add missing includes of <system_error> for std::error_code

This fixes compilation with MinGW after SVN r333798, which added
a few functions within _WIN32 ifdefs, functions returning
std::error_code. Include everything that is needed instead of
hoping that this header being inclued transitively (which it apparently
is in MSVC builds).
