Compute Decider's CM challenges in Groth16 circuit, link G16 & KZG proofs in Onchain Decider, refactor CommitmentScheme trait (#79)

* Compute Decider's CM challenges in Groth16 circuit, link G16 & KZG proofs in Onchain Decider, refactor CommitmentScheme trait

- Refactor commitment package
  - Refactor `Commitment` trait and the kzg, ipa, pedersen impls
  - Add methods to prove & verify given challenges (not computing them in-method)
- Add KZG challenges computation in decider_eth_circuit
- Add cmE & cmW KZG proving & verification in DeciderEth
- Link Decider's Groth16 proof & KZG proofs data
- Fix point to bytes arkworks inconsistency
- Patch ark_curves to use a cherry-picked version with bn254::constraints & grumpkin for v0.4.0 (once arkworks v0.5.0 is released this will no longer be needed)

* DeciderEthCircuit: Add check eval=p(c) for E & W

The check is temporary disabled due
https://github.com/privacy-scaling-explorations/folding-schemes/issues/80,
but the public inputs and logic are there, to be able to continue the
other parts development while issue #80 is solved.
