feat(tvix/boot): support seeding closures via nar-bridge r/7727

This updates the parameters mkBootTest can be called with. It now
accepts a `path`, and then either importPathName needs to be set, or
isClosure needs to be set to true.

The former activates the existing functionality, tvix-store import is
used to import contents  as a NAR-addressed store path.
The latter uploads the path as a closure (so including its references,
and keeping the store paths intact) to tvix-store.
We use nar-bridge, and the HTTP interface it provides to do this.
As `nix copy` can't be used inside a Nix build, we use
`pkgs.mkBinaryCache` to come up with the .narinfo and .nar files that
would be in a binary cache, and then use a bit of GNU Parallel and bash
to upload store paths ourselves.
