[benchmarking] Reset to genesis storage after each run (#5655)

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.
