Include libz.a in native aot packages

[jkotas]

Fixes #106566

[jkotas]

@carlossanlop This would be my fix. It gets rid of the Windows/Unix divergence and centralizes the workaround in a single place in Microsoft.NETCore.Native.Unix.targets

[carlossanlop]

I'll trigger some extra azp runs to confirm nothing breaks.
If it all looks good, we will need get it backported to release/9.0.
