consumer bench same number of txs per iteration

[apfitzge]

Problem

Comment #34717 (comment) for similar benchmark of the block-validation execution path. Bench results of different batch sizes are directly comparable if we always execute the same number of txs per bench iteration.

Summary of Changes

Run same number of txs per bench iteration in consumer benchmarks.
