This change adds documentation to quite a few existing public types that didn't have a blurb before. Additionally, this fixes a couple things that I think either didn't make sense when going to document them: - Rename ConnectionStream to VsockConnectionStream. This type only functions for vsock connections. - Deletes NsLock+Closure. This was not used anywhere. - Rename ContainerizationOCI/Config.swift to ImageConfig.swift.
