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

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.

Bulk: Pass slot origin to legality analysis. Pass the proper personal data for good measure
Personal: check if the form truly does exist for presence check because sometimes the form will default to 0 on OOB
Showdown: Reduce some allocation, be more lenient in casing parse for Nature suffix and Hidden Power manually typed by user. Parse non-english hidden power sets (yay, now usable by all languages even though PS sets are English only!).
Will need to verify if Beast Balls can be used on other Pokémon, and if generic Poké Balls can be used on Ultra Beasts. We'll see when GO Fest Berlin starts.
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.
New current handler verifier settings flag GO => LGPE transfers. Unlike GO => HOME, these transfers use your LGPE OT info, so it's legal to have no HT and have the current handler be OT

Default settings do not flag, as Database view does not track the savefile (LegalityAnalysis only indirectly references the latest loaded save file, not the true source).
Bulk Analysis will flag them correctly if run. Can be turned off.
* 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.
