This replaces the hello world example from tvix-store with an actual
gRPC endpoint, implementing all of BlobService, DirectoryService and
PathInfoService.
All RPC methods currently respond with the unimplemented gRPC status.

This implements the nix-specific base32 encoding and decoding, exposing
a subset of the API that the data-encoding crate provides.
Nix uses a custom alphabet, no padding, and encodes bytes in reverse
order. The latter one is the reason we can't just use the data-encoding
crate directly.
Three odd corner case tests ported over from go-nix failed. We opened
b/235 to further investigate.

Stat exposes metadata about a given blob,
such as more granular chunking, baos.
It implicitly allows checking for existence too, as asking this for a
non-existing Blob will return a Status::not_found grpc error.
The previous version returned a Status::not_found error on the Get
request too, but there was no chance to prevent the server from starting
to stream (except sending an immediate cancellation).
Being able to check whether something exists in a BlobStore helps to
prevent from uploading in first place.
The granular chunking bits are an optional optimization - if the
BlobStore implements no more granular chunking, the Stat response can
simply contain a single chunk.
Read returns a stream of BlobChunk, which is just a stream of bytes -
not necessarily using the chunking that's returned in the reply of a
Stat() call. It can be used to read blobs or chunks.

Expose the NAR calculation to a separate `CalculateNAR` method, which
responds with the NAR size and sha256 hash.
Contrary to what cl/7618 and cl/7620 initially did, don't add different
other request types.
In the CalculateNARResponse message, there's now some duplication in the
(optional) `narinfo` field of a PathInfo, but I'm not entirely sure if
we want to drop the fields from there yet.

Introduces granular dependency builds using crate2nix, bootstrapped
off the generated configuration from the newly introduced
workspace (see cl/7533).
This commit checks in the generated Cargo.nix file which can be
regenerated with a parameterless invocation of `crate2nix generate` in
`//tvix`. I tried generating this in IFD, but it turned out to be
harder than what seemed worthwhile for now.
In this setup, the various build targets for Rust projects end up
being attributes of the imported `Cargo.nix` file at the `tvix.crates`
attribute. These still lack configuration, however, which has been
fixed in the various `default.nix` files of individual projects.
Note that we (temporarily) lose the ability to build tvix-eval's
benchmarks in CI. I haven't figured out what magic incantation summons
them from the void again ...
The `eval-okay-readDir` tests from both test suites have been disabled
because they fail for unknown reasons when run in this new derivation.
Somebody will have to debug it!

This relates to the (abandoned) cl/7256.
Introduces a Cargo workspace at //tvix that is primarily intended to
be used as a workaround for the annoying Nix+Rust tooling while having
a consistent set of dependencies.
This is driven in part by a desire to adopt crate2nix and get more
granular Nix builds for Tvix's Rust projects, and in part by a need to
split //tvix/eval into something providing the CLI (REPL etc.), and a
library providing eval, without significantly altering the structure
of build targets.
To accomplish this the workspace has been designed to allow projects
to remain independent build targets. I want to avoid lumping all the
projects together - something like //tvix/eval should always be
independent of other parts of tvix.
A helper function in //tvix/default.nix lets downstream naersk
projects construct a sparse root for the project which combines the
workspace's `Cargo.lock` with the project's own `Cargo.toml`.
Note that cargo commands in the workspace itself require the build
dependencies of _all_ projects to be present, which is currently a bit
annoying to accomplish.
This introduces some breakage:
1. It breaks usage of rust-analyser without being in a shell with the
dependencies of *all* Tvix projects, as it is not capable of
respecting only the subset of dependencies for a part of the
workspace.
2. It is no longer possible to run tests using `cargo test`, as the
test generation crate we use does not work with workspaces:
https://github.com/frehberg/test-generator/issues/6
This still works in the Nix build as we construct a Cargo project
that looks like it's not in a workspace there. Until somebody fixes
that crate / writes a new macro / does something else with the test
suite, the way to run the tests is through the Nix build.
Long-term we'll probably want to get rid of cargo completely, it's
just a big wart and most tooling works without it if correctly
configured, but we don't have time for that now.
