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.

Currently CAHash only deserializes the hash in hex code while
the serializer outputs a nixbase32 hash. This means that you can't currently
deserialize what has been serialized.
This change makes deserialize support any digest format (so hex, nixbase32
and base64) as well as flattens the deserialize code and error handling.
It also implements serde methods of HashAlgo directly using Display and TryFrom
implementations because otherwise these would get serialized as eg. Sha256 instead
of sha256 which also broke CAHash serialize/deserialize.

This doesn't return the digest, but the internal NixHash.
To get the digest, you use `ca_hash.hash().digest_as_bytes()`

Instead of constructing a completely new derivation for hashing,
allow to call hashing with substituted input_derivations.
This
1. reduces the number of allocations,
2. prepares substituting `String`s for store paths with proper `StorePath`s without needing a separate derivation struct that allows hashes without `/nix/store` in input_derivations, and
3. keeps the change local to the `Derivation` implementation.

Nix is quite tolerant when it comes to parsing SRI hashes and their
padding (and only for SRI hashes, it funnily is strict about that in the
non-SRI-hash case).
Nix essentially accepts any number of padding characters, no matter if
it's too much or too little. So we do the only sane thing - simply strip
all padding characters, and parse it with BASE64_NOPAD and the length
the algo uses.
