feat(tvix/store/bin): add "copy" command

Browse source 
This allows copying individual store paths from the local /nix/store
into tvix-store.

As we don't support getting this information from Nix yet, we currently
expect metadata to be provided externally:

Nix' `exportReferencesGraph` feature contains pretty much all data we
need for this. Expect a list of this information at a well-known key
(`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/
default.nix`).

We currently simply upload all store paths sequentially, without any
parallelism or awareness in how the reference graph looks like.

As long as the connected stores don't enforce this, this is fine, at
least for now.
