strerror: use sys_errlist instead of strerror on Windows
- Change Curl_strerror to use sys_errlist[errnum] instead of strerror to retrieve the error message on Windows. Windows' strerror writes to a static buffer and is not thread-safe. Follow-up to 2f0bb86 which removed most instances of strerror in favor of calling Curl_strerror (which calls strerror_r for other platforms). Ref: https://github.com/curl/curl/pull/7685 Ref: https://github.com/curl/curl/commit/2f0bb86 Closes https://github.com/curl/curl/pull/7735
