Description

We need to ramp up required hashes per tick to keep validators busier based on analysis in https://docs.google.com/spreadsheets/d/1NDJZiSFxqbVIi0jn-7I7MrYN2lqP4j9GePZdyPZ1fhI/edit#gid=1060803070

#33600 Adds several discrete values to ramp up the required hashes per tick as these features get activated.

All nodes need to adopt the same hashes per tick at the same time otherwise we will see consensus mismatches due to differing block hashes.

Deployment Considerations

PoH sleep/hash rate metrics will need to be monitored to ensure analysis on achievable hashes per second and hashes per tick continues to hold up.

Mainnet validators are busying hashing ~81% of the time on average after enabling this feature gate
