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
Closes#3519
Usages weren't consistent; since `é` isn't accessible on usual english keyboards, just use regular `e` instead of alt-223 entry.
Not sure why VS preferred to save the text files without an encoding prefix; oh well.
* Revises legality checks to account for traveling between the three game islands (PLA/BDSP/SWSH)
* Adds conversion mechanisms between the three formats, as well as flexible conversion options to backfill missing data (thanks GameFreak/ILCA for opting for lossy conversion instead of updating the games).
* Adds API abstractions for HOME data storage format (EKH/PKH format 1, aka EH1/PH1).
* Revises some APIs for better usage:
- `PKM` now exposes a `Context` to indicate the isolation context for legality purposes.
- Some method signatures have changed to accept `Context` or `GameVersion` instead of a vague `int` for Generation.
- Evolution History is now tracked in the Legality parse for specific contexts, rather than only per generation.
Future-proofing. We know that Hisuian Zoroark is in SV, as well as Petilil, so if Hisuian Lilligant is also present, we need to not show Lady Lilligant in the form dropdown for those games.
Also only show Primal Kyogre/Groudon for Gens 6/7 (can be revised later if they come back in SV).
ty @Atrius97 for finally nailing the repro on this

Only allocations that remain are the runtime `new string(...)` that is required for the gen1-5 species name quirks.
Inlines some logic for language fetch, and requires slightly less memory.
Many years ago, PKX used to be a >4,000 line bloated file, which spun off multiple classes like CommonEdits and most of the early non-GUI PKM related logic. Now, it's just a stub to source the latest generation & personal table.
Separate files = more concise info, and more room to grow to do more advanced things.
Makes the IsPresent methods public (no longer internal).
