refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crate r/6550
This trait is eval-specific, there's no point in dealing with these things in tvix-store. This implements the EvalIO interface for a Tvix store. The proper place for this glue code (for now) is tvix-cli, which knows about both tvix-store and tvix-eval. There's one annoyance with this move: The `tvix-store import` subcommand previously also used the TvixStoreIO implementation (because it conveniently did what we wanted). Some of this code had to be duplicated, mostly logic to calculate the NAR-based output path and create the PathInfo object. Some, but potentially more of this can be extracted into helper functions in a shared crate, and then be used from both TvixStoreIO in tvix-cli as well as the tvix-store CLI entrypoint.
