feat(tvix/glue): use TvixStoreIO as derivation builtin state r/7410

We propagate a `TvixStoreIO` as the `state` of our derivation-specific
builtins in the glue crate.

The evaluators `io_handle` itself is using a Rc<dyn EvalIO>.

An earlier version of TvixStoreIO was also introducing generics over the
different internal services themselves, but we opted for instead
hardcoding this to Arc<dyn …> for the sake of less macro voodoo.
