Add KZG Support for EIP-4844 Blobs

[BlazeWasHere]

Plan is to allow users to create commitments for blob data they have and then serialize the blobVersionedHashes into an EIP-4844 transaction similar to how ethers.js does it https://github.com/ethers-io/ethers.js/issues/4650#issuecomment-2023747487

The KZG library will be optional for users as the majority of users will not be creating and posting blobs to the chain

KZG could be https://github.com/ethereum/c-kzg-4844 as a NIF
