Add a `cargo_criterion_support` feature flag

[str4d]

This enables cargo-criterion support to be compiled out if it is not required. A compile-time error is added to require that at least one of [cargo_bench_support, cargo_criterion_support] must be enabled.

I'm not sure what we should do about cargo_bench_support. The benefits of using criterion without cargo bench support seem very minor to me. Unless there is a compelling use-case, I think we should keep cargo_bench_support as a dummy feature that does nothing.
