Provide binary download for windows arm64

There is currently no binary download of ODBC connector (or server) available for windows arm64. While it would be nice to have a native version of both server and ODBC connector for windows arm64 versions the absence of a native arm64 ODBC connector means that native arm64 software cannot communicate via ODBC with the server. Affects current release and all earlier releases. The only workaround at present is to build your own from source! Windows on arm64 is an environment which is rapidly increasing in usage. For example windows VM's on Apple Silicon, MS Surface devices etc.
