Refactor EvoCriteria to be a struct, reduce allocation (#3483)
* Make EvolutionCriteria struct

8 bytes per object instead of 26
Unify LevelMin/LevelMax to match EncounterTemplate
bubble up precise array type for better iteration

* Inline queue operations, less allocation

* Inline some logic

* Update EvolutionChain.cs

* Improve clarity on duplicate move check

* Search reverse

For a dual stage chain, finds it first iteration rather than second.
