feat(tvix): add CI targets for checking crate features powerset 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`.

refactor(tvix): move tvix glue code into glue crate There's various bits and pieces in tvix-cli that use both the store and evaluator, as well as nix-compat. For example, builtins.derivation, as well as the reference scanning implementation. This "glue code" currently isn't accessible from anywhere else, but it'd be very useful if it were. Move it out into a `glue` crate, and make `tvix-cli` a consumer of it. All the KnownPaths setup and passing around, as well as NIX_PATH handling is also something that should probably be moved into the glue crate as well, but that's something left for a future CL.

feat(tvix/glue): Implement builtins.fetchurl Implement the fetchurl builtin, and lay the groundwork for implementing the fetchTarball builtin (which works very similarly, and is implemented using almost the same code in C++ nix). An overview of how this works: 1. First, we check if the store path that would result from the download already exists in the store - if it does, we just return that 2. If we need to download the URL, TvixStoreIO has an `http_client: reqwest::Client` field now which we use to make the request 3. As we're downloading the blob, we hash the data incrementally into a SHA256 hasher 4. We compare the hash against the expected hash (if any) and bail out if it doesn't match 5. Finally, we put the blob in the store and return the store path Since the logic is very similar, this commit also implements a chunk of `fetchTarball` (though the actual implementation will likely include a refactor to some of the code reuse here). The main thing that's missing here is caching of downloaded blobs when fetchurl is called without a hash - I've opened b/381 to track the TODO there. Adding the `SSL_CERT_FILE` here is necessary to teach reqwest how to load it during tests - see 1c16dee20 (feat(tvix/store): use reqwests' rustls-native-roots feature, 2024-03-03) for more info.
