5a97888d8b chore(tvix): Migrate members to inherit deps from workspace
From now on we will add the dependencies and their version in the root
Cargo.toml and in order to enable the dependency for a workspace member
we set `workspace = true` in the member's Cargo.toml.

2945a359b4 chore(tvix): Bump versions of all compatible deps via cargo upgrade
This updates all the dependencies and their "minimum" versions in
Cargo.{lock,toml} to the latest compatible version using `cargo-edit`'s
`cargo upgrade` command that will eventually be merged into `cargo
update`.

201173afac fix(tvix): Represent strings as byte arrays
C++ nix uses C-style zero-terminated char pointers to represent strings
internally - however, up to this point, tvix has used Rust `String` and
`str` for string values. Since those are required to be valid utf-8, we
haven't been able to properly represent all the string values that Nix
supports.

To fix that, this change converts the internal representation of the
NixString struct from `Box<str>` to `BString`, from the `bstr` crate -
this is a wrapper around a `Vec<u8>` with extra functions for treating
that byte vector as a "morally string-like" value, which is basically
exactly what we need.

Since this changes a pretty fundamental assumption about a pretty core
type, there are a *lot* of changes in a lot of places to make this work,
but I've tried to keep the general philosophy and intent of most of the
code in most places intact. Most notably, there's nothing that's been
done to make the derivation stuff in //tvix/glue work with non-utf8
strings everywhere, instead opting to just convert to String/str when
passing things into that - there *might* be something to be done there,
but I don't know what the rules should be and I don't want to figure
them out in this change.

To deal with OS-native paths in a way that also works in WASM for
tvixbolt, this also adds a dependency on the "os_str_bytes" crate.

c8fcdca4eb feat(tvix/eval): allow extending builtins outside of tvix_eval
The change allows applications that use tvix_serde for parsing
nix-based configuration to extend the language with domain-specific
set of features.

90c32eec7a feat(tvix/serde): initial Nix->serde::Deserialize impl
This will make it possible fairly easily use Nix to represent
arbitrary data structures, e.g. for using Nix as a config language.

Only pure Nix (i.e. no `import` etc.) is supported for now.

Not all types, specifically no struct traversal, are implemented in
this commit.
