abstract: Tests full blob type transactions for EIP-4844: Shard Blob Transactions

Test full blob type transactions for [EIP-4844: Shard Blob Transactions](https://eips.ethereum.org/EIPS/eip-4844).

test_reject_valid_full_blob_in_block_rlp(blockchain_test, pre, env, blocks)

Test valid blob combinations where one or more txs in the block serialized version contain a full blob (network version) tx.
