Add missing circuits to benchmarks

[ed255]

We have benchmark tests defined here: https://github.com/privacy-scaling-explorations/zkevm-circuits/tree/main/circuit-benchmarks/src

We need to include the following circuits:

• [x] PublicInputs #830
• [x] Bytecode https://github.com/privacy-scaling-explorations/zkevm-circuits/pull/807
• [x] Copy #899
• [x] full Keccak #634
• [ ] Exp Circuit https://github.com/privacy-scaling-explorations/zkevm-circuits/pull/980

We are working on it.

@ed255 looks like all missing benches are done. Do we need exp circuit bench as in #980?

Thanks for reviewing this! We should have benches for all circuits. Let me extend this issue to include the Exp Circuit and once it's merged we can close this :)
