39efe50311 refactor(tvix/nix-compat/derivation/escape): move to Vec<u8>
We only need bstr::ByteSlice to be able to use replace, it doesn't need
to return a BString.

aa1982c085 refactor(tvix/derivation): move comma writing business up

42dc18353d feat(tvix/nix-compat): have StorePath accept bytes
The primary constructor for this is now from_bytes, from_string is
simply calling .as_bytes() on the string, passing it along.

The InvalidName error now contains a Vec<u8>, to encode the invalid name
(which might not be a string anymore).

from_absolute_path now accepts a &[u8] (even though we might want to
make this a OSString of some sort).

StorePath::validate_name has been degraded to a pub(crate) function.
It's still used in src/derivation, even though it probably shouldn't at
all - that cleanup is left for cl/8412 though.

26c68f8e89 refactor(nix-compat): Properly encapsulate store path construction
Before there was code scattered about (e.g. text hashing module and
derivation output computation) constructing store paths from low level
building blocks --- there was some duplication and it was easy to make
nonsense store paths.

Now, we have roughly the same "safe-ish" ways of constructing them as
C++ Nix, and only those are exposed:

- Make text hashed content-addressed store paths

- Make other content-addressed store paths

- Make input-addressed fixed output hashes

5f2c2e79e1 refactor(tvix/nix-compat): move build_store_path out of derivation
This doesn't have anything to do with ATerms, we just happen to be using
the aterm representation of a Derivation as contents.

Moving this into store_path/utils.rs makes these things much cleaner -
Have a build_store_path_from_references function, and a
build_store_path_from_fingerprint helper function that makes use of it.

build_store_path_from_references is invoked from the derivation module
which can be used to calculate the derivation path.

In the derivation module, we also invoke
build_store_path_from_fingerprint during the output path calculation.

6454769eef refactor(tvix/nix-compat): drop is_derivation in build_store_path
This only added a suffix to the input argument, if build_store_path was
building the path of a Derivation.

As we need to also add the `.drv` suffix to the name we pass into
text_hash_string inside calculate_derivation_path, we can simply add the
suffix there and drop the parameter from build_store_path.

b55d1f97ce refactor(tvix/nix-compat): -derivation::Hash, +NixHash
This stops using our own custom Hash structure, which was mostly only
used because we had to parse the JSON representation somehow.

Since cl/8217, there's a `NixHash` struct, which is better suited to
hold this data. Converting the format requires a bit of serde labor
though, but that only really matters when interacting with JSON
representations (which we mostly don't).
