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.

Both //tvix/eval and //tvix/nix_cli have need to for rust tooling available
in $PATH.
Move this one level up, so it's accessible in all subdirectories.

This exposes tvix.nix_cli as a proper attribute to readTree, so it's
actually built by CI.

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.
