feat(tvix): add CI targets for checking crate features powerset r/8211

Closes: https://b.tvl.fyi/issues/401

With this change all crate features (and their combinations) will be built and
tested in CI.

From now on, when adding/removing a Cargo feature for a crate,
you will want to add it to the features power set that gets tested in CI.
For each crate there's a default.nix with a `mkFeaturePowerset` invocation,
modify the list to include/remove the feature.
Note that you don't want to add "collection" features,
such as `fs` for tvix-[ca]store or `default`.
