sspi: Refactored socks_sspi and schannel to use same error message functions
Moved the error constant switch to curl_sspi.c and added two new helper functions to curl_sspi.[ch] which either return the constant or a fully translated message representing the SSPI security status. Updated socks_sspi.c and curl_schannel.c to use the new functions.
