fix: slot, round and forgingInfo calculation for dynamic block times

[sebastijankuzner]

Summary

This PR fixes invalid handling of dynamic blockTime in milestones. Affected are Slots from packages/crypto and calculate-forging-info from packages/core-kernel.

Fixes now calculate valid data for static and dynamic blockTime and are supported by valid test.

Because of similar logic logic there is also refactored core-kernel/round-calculator.
