[build] Don't rebuild managed code on packaging time on Windows

Rebuilding the managed code on Windows causes it to want to use
`msvcrt` instead of `c` when resolving `libc` p/invokes, which
will cause the libc calls to fail on Unix.

Download and extract the `Managed` artifact on packaging time, so
that the assemblies built on Unix are properly packaged and not
rebuilt.
