The tvix-eval project is independent from any *uses* of the evaluator,
such as the tvix-repl.
This functionality has been split out into a separate "tvix-cli"
crate. Note that this doesn't have to mean that this CLI crate is the
"final" CLI crate for tvix, the point of this is not "getting the CLI
structure right" but rather "getting the evaluator structure right".
This reshuffling is part of restructuring the way that functionality
like store communication is injected into language evaluation.
Note that at this commit the new CLI crate is not at feature-parity.

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.

For some reason a top-level Rust project ended up in this location,
which is incompatible with the actual project structure that's being
prepared for merge right now.

We are going to have a 1:1 drop-in replacement for the old-style nix
tools, and this starts implementing the cli parser part.
The first step is to have a simple integration test suite that can
verify that we match the nix CLI.
clap is a super complicated parsing library, but looking through the
rest they are either too opinioated to be of use for us, or depend on
clap as implementation.
