core/vm, params: ensure order of forks, prevent overflow (#29023)

Browse Source 
This PR fixes an overflow which can could happen if inconsistent blockchain rules were configured. Additionally, it tries to prevent such inconsistencies from occurring by making sure that merge cannot be enabled unless previous fork(s) are also enabled.
