Serializes a #GIcon into a #GVariant. An equivalent #GIcon can be retrieved
back by calling gio.icon.Icon.deserialize on the returned value.
As serialization will avoid using raw icon data when possible, it only
makes sense to transfer the #GVariant between processes on the same machine,
(as opposed to over the network), and within the same file system namespace.
