feat(tvix/cli): add macrobenchmark r/7163
This commit adds a simple MVP benchmark, built on our nix infrastructure instead of cargo. It simply runs `tvix-eval` inside of GNU time, and prints the three essential statistics in a short JSON blob. You can run the benchmark with a simple `nix run`, like: nix run -f . tvix.cli.benchmark-hello nix run -f . tvix.cli.benchmark-firefox nix run -f . tvix.cli.benchmark-cross-firefox Currently these blobs are stored only in the CI logs, which I'm sure get garbage-collected at some point. We should be putting them in the git trailers, but that can wait for a future CL. I tried using `cargo bench` for this but found it incredibly frustrating. Maybe I'm doing it wrong. It seems to be designed for microbenchmarks only, and very hard to control. It kept building all sorts of unnecessary stuff (like the tests), and unlike crate2nix it was doing all the builds on only a single machine instead of using more than one machine. Worse, for that single machine it kept picking my laptop instead of my fast servers! It seems excessively cargo-flavored for such a straightforward task.
