feat(tvix/store): add write_nar function r/5794
This adds a function that consumes a [proto::node::Node] pointing to the
root of a (store) path, and writes the contents in NAR serialization to
the passed [std::io::Write].

We need this in various places:

 - tvix-store's calculate_nar() RPC method needs to render a NAR stream
   to get the nar hash, which is necessary to give things imported in
   the store a "NAR-based" store path.

 - communication with (remote) Nix (via daemon protocol) needs a NAR
   representation.

 - Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a
   NAR representation.
