cmake: Fix symlink on Windows

Browse Source 
Copy the old glslangValidator name on Windows rather than creating a
symlink. While cmake 3.13 and above supports creating symlinks on
Windows, a security policy change is required in general to allow
the creation of symlinks for non-trusted users. See
https://learn.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/create-symbolic-links

Fixes #3268.
