get unlimted txns from txpool
erigon miner use cfg.txPool2.Best(200, &txSlots, poolTx)) to fetch 200 txns in SpawnMiningCreateBlockStage , but geth miner will fetch as much txns as possible from txpool and only conside gaslimit when commitTrancations in execution, so can we change Best(200) to Best(INT.MAX) to make miner more efficent? and let erigon execution stage to judge whether it has exceed limit (this code already realized in the picture in stage_mining_exec.go)
