Disallow Mozc to be installed on ARM64 Windows

Before Mozc becomes available to ARM64 processes in Windows, let's disallow Mozc64.msi to be installed into ARM64 Windows machines to avoid unnecessary user confusions. Note that this commit only blocks the initial installation. There is no behavior change for those who have already installed Mozc into their ARM64 Windows environments. This means that both upgrading from a previous version of Mozc and uninstalling Mozc continue to be allowed. Closes google#1127.
