Make GetG3Species return ushort
Fixes regression caused by 5942a74147
Copying SpeciesID3 instead of Species is fine as it skips the map/unmap step, but it also skips the setting of the HasSpecies flag. So we'll just set it in the individual ConvertToPK3 methods.
Rewrites a good amount of legality APIs pertaining to:
* Legal moves that can be learned
* Evolution chains & cross-generation paths
* Memory validation with forgotten moves
In generation 8, there are 3 separate contexts an entity can exist in: SW/SH, BD/SP, and LA. Not every entity can cross between them, and not every entity from generation 7 can exist in generation 8 (Gogoat, etc). By creating class models representing the restrictions to cross each boundary, we are able to better track and validate data.
The old implementation of validating moves was greedy: it would iterate for all generations and evolutions, and build a full list of every move that can be learned, storing it on the heap. Now, we check one game group at a time to see if the entity can learn a move that hasn't yet been validated. End result is an algorithm that requires 0 allocation, and a smaller/quicker search space.
The old implementation of storing move parses was inefficient; for each move that was parsed, a new object is created and adjusted depending on the parse. Now, move parse results are `struct` and store the move parse contiguously in memory. End result is faster parsing and 0 memory allocation.
* `PersonalTable` objects have been improved with new API methods to check if a species+form can exist in the game.
* `IEncounterTemplate` objects have been improved to indicate the `EntityContext` they originate in (similar to `Generation`).
* Some APIs have been extended to accept `Span<T>` instead of Array/IEnumerable
was checking stale value
make loop max adjustable by caller; knowingly requesting squares is 1:65,536, so a higher loop count than 50k might guarantee more successes.
Maybe in the future we'd have separate algorithms to pre-choose seeds by choosing a PID and unrolling -> rolling.

apparently Japanese XD uses 32bit instead of 64bit, different struct size. Seems the same as the memo size being different for japanese XD too.
Since we're now using Config, apply the correct CurrentRegion/OriginalRegion values when setting a pk* to sav.
