ccf87242c1 Eliminate boxing on encounter search (criteria)
struct implementing interface is boxed when passed to method that accepts interface (not generic method).
Removes IDexLevel (no other inheritors but EvoCriteria) and uses the primitive the data is stored (array, not IReadOnlyList) for slightly better perf.

Refactor EvoCriteria to be a struct, reduce allocation ()
* 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.

efb3d9aeac Add inaccessible den-rank checks
Rotom Bike water upgrade isn't available until you have sufficient progress, so you can't get these dens with the lowest rank.

Fracture the encounter matching checks to allow progressive validation ()
## Issue

We want to discard-but-remember any slots that aren't a perfect fit, on the off chance that a better one exists later in the search space. If there's no better match, then we gotta go with what we got.

## Example:
Wurmple exists in area `X`, and also has a more rare slot for Silcoon, with the same level for both slots. 
* We have a Silcoon that we've leveled up a few times.

Was our Silcoon originally a Wurmple, or was it caught as a Silcoon? 
* To be sure, we have to check the EC/PID if the Wurmple wouldn't evolve into Cascoon instead.
* We don't want to wholly reject that Wurmple slot, as maybe the Met Level isn't within Silcoon's slot range.

---

Existing implementation would store "deferred" matches in a list; we only need to keep 1 of these matches around (less allocation!). We also want to differentiate between a "good" deferral and a "bad" deferral; I don't think this is necessary but it's currently used by Mystery Gift matching (implemented for the Eeveelution mystery gifts which matter for evolution moves).

The existing logic didn't use inheritance, and instead had static methods being reused across generations. Quite kludgy. Also, the existing logic was a pain to modify the master encounter yield methods, as one generation's quirks had to not impact all other generations that used the method.

---

The new implementation splits out the encounter yielding methods to be separate for each generation / subset. Now, things don't have to check `WasLink` for Gen7 origin, because Pokémon Link wasn't a thing in Gen7.

---

## Future
Maybe refactoring yielders into "GameCores" that expose yielding behaviors / properties, rather than the static logic. As more generations and side-gamegroups get added (thanks LGPE/GO/GameCube), all this switch stuff gets annoying to maintain instead of just overriding/inheritance.

## Conclusion

This shouldn't impact any legality results negatively; if you notice any regressions, report them! This should reduce false flags where we didn't defer-discard an encounter when we should have (wild area mons being confused with raids).

remove GetMinimalLevel override, as it's doing the same thing as LevelMin. When regenerating the pkm, we aren't doing anything downlevel related.
