eth, miner: use miner for post-merge block production (#23256)
* eth, miner: remove duplicated code * eth/catalyst: remove unneeded code * miner: keep update pending state even the Merge is happened * eth, miner: rebase * miner: fix tests * eth, miner: address comments from marius * miner: use empty zero randomness for pending blocks after the merge * eth/catalyst: gofmt * miner: add warning log for state recovery * miner: ignore uncles for post-merge blocks Co-authored-by: Péter Szilágyi <peterke@gmail.com>
