build/win: Add workaround for Windows command length limit

Browse Source 
When building with the Ninja generator on Windows, it was possible for
the external_blobs target to fail when the generated command exceeds the
command length limit (8191 characters). To workaround the problem, a
CMake script is used to copy the files instead of a shell command.
