[benchmarking] Reset to genesis storage after each run

[ggwpez]

The genesis state is currently partially provided via OverlayedChanges, but these changes are reset by the runtime after the first repetition, causing the second repitition to use an invalid genesis state.

Changes:

• Provide the genesis state as a Storage without any OverlayedChanges to make it work correctly with repetitions.
• Add --genesis-builder-preset option to use different genesis preset names.
• Improve error messages.

@ggwpez Anything speaks against merging this? I have a follow up that could share some code.

This fix is working finally for short-benchmarking with omni-bencher for bridge-hubs/collectives: https://github.com/paritytech/polkadot-sdk/actions/runs/10983379680/job/30492700127?pr=5706 https://github.com/paritytech/polkadot-sdk/actions/runs/10983379680/job/30492700240?pr=5706 https://github.com/paritytech/polkadot-sdk/actions/runs/10983379680/job/30492700384?pr=5706 so merging this
