Move benchmarks to Rust (#7134)
All benchmarks are done in Rust and can be invoked with
`cargo bench`.

Currently this has it's own "harness" that behaves like
`./tools/benchmark.py` did.
Because of this tests inside `cli/bench` are currently not run.
This should be switched to the language provided harness
once the `#[bench]` attribute has been stabilized.
