EIP-7594: PeerDAS

[daniellehrner]

In order allow PeerDAS to include more blobs per block the proof computation is offloaded to the tx sender. This requires changes in the EL clients as well.

See this doc for more context:

A PR has been created to include the EL changes in the EIP:
ethereum/EIPs#9378

First assessment of the changes:

*) The PR specifies that 4844 txs should be changed at the hard fork block to include cell proofs instead of the kzg proof. We currently have no way of changing tx decoding / validation at hardforks, onkly including new ones or removing old ones.
*) We either need to build that into Besu or propose to do a new transaction type instead. I am currently in favor of the latter
*) We need to update c-kzg-4844 to use the latest main version. The method to validate the new transactions has been added
*) A new TransactionDecoder and TransactionEncoder needs to be created for those new transactions
*) MainnetTransactionValidator needs to be updated to validate those transactions: https://hackmd.io/@fradamt/mempool-change
*) Increase size in BlobCache
