Add Fulu fork boilerplate (#14771)

* Prepare for future fork boilerplate.

* Implement the Fulu fork boilerplate.

* `Upgraded state to <fork> log`: Move from debug to info.

Rationale:
This log is the only one notifying the user a new fork happened.
A new fork is always a little bit stressful for a node operator.
Having at least one log indicating the client switched fork is something useful.

* Update testing/util/helpers.go
