bench pallet: only require Hash instead of Block (#3244)

Preparation for https://github.com/paritytech/polkadot-sdk/issues/2664

Changes:
- Only require `Hash` instead of `Block` for the benchmarking
- Refactor DB types to do the same

## Integration

This breaking change can easily be integrated into your node via:  
```patch
- cmd.run::<Block, ()>(config)
+ cmd.run::<HashingFor<Block>, ()>(config)
```

Status: waiting for CI checks
