crypto/kzg4844: add ComputeCells functionality (#31378)
For PeerDAS, we need to compute cell proofs. Both ckzg and gokzg support computing these cell proofs. This PR does the following: - Update the go-kzg library from "github.com/crate-crypto/go-kzg-4844" to "github.com/crate-crypto/go-eth-kzg" which will be the new upstream for go-kzg moving forward - Update ckzg from v1.0.0 to v2.0.1 and switch to /v2 - Updates the trusted setup to contain the g1 points both in lagrange and monomial form - Expose `ComputeCells` to compute the cell proofs
