Refactor fork schedules (#15490)

* overhaul fork schedule management for bpos

* Unify log

* Radek's comments

* Use arg config to determine previous epoch, with regression test

* Remove unnecessary NewClock. @potuz feedback

* Continuation of previous commit: Remove unnecessary NewClock. @potuz feedback

* Remove VerifyBlockHeaderSignatureUsingCurrentFork

* cosmetic changes

* Remove unnecessary copy. entryWithForkDigest passes by value, not by pointer so it shold be fine

* Reuse ErrInvalidTopic from p2p package

* Unskip TestServer_GetBeaconConfig

* Resolve TODO about forkwatcher in local mode

* remove Copy()
