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
* 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.
Sweet Heart still unobtainable (why did they give it a sprite if it's not functional ingame?)
Azure Flute is now obtainable
Sacred Ash was never obtainable
As you progress the story in the Sinnoh games, the water level in Lake Verity will rise allowing you to Surf and reach the Verity Cavern. When this happens differs between DP/BDSP and Pt.
Zone 323 has nothing to do with it being early-game and only when Rowan's briefcase is present, but rather the differing water level. Riley's Riolu Egg can be hatched here without trading, as well.

Closes#3318
Gen8: if held item, only give if can be legally held; if dmax crystal, only give if available.
Gen8b: if held item, only give if can be legally held
Others: unimplemented; pull requests accepted.
Big thanks to @SciresM @sora10pls @Lusamine @architdate @ReignOfComputer for testing and contributing code / test cases. Can't add co-authors from the PR menu :(
Builds will fail because azure pipelines not yet updated with net6.
They cannot be given to a Pokémon to hold in-game. Also label new Pikachu/Eevee Dynamax Crystals.

* Track a PKM's Box,Slot,StorageFlags,Identifier metadata separately
Don't store within the object, track the slot origin data separately.
Batch editing now pre-filters if using Box/Slot/Identifier logic; split up mods/filters as they're starting to get pretty hefty.
- Requesting a Box Data report now shows all slots in the save file (party, misc)
- Can now exclude backup saves from database search via toggle (separate from settings preventing load entirely)
- Replace some linq usages with direct code
* Remove WasLink virtual in PKM
Inline any logic, since we now have encounter objects to indicate matching, rather than the proto-legality logic checking properties of a PKM.
* Use Fateful to directly check gen5 mysterygift origins
No other encounter types in gen5 apply Fateful
* Simplify double ball comparison
Used to be separate for deferral cases, now no longer needed to be separate.
* Grab move/relearn reference and update locally
Fix relearn move identifier
* Inline defog HM transfer preference check
HasMove is faster than getting moves & checking contains. Skips allocation by setting values directly.
* Extract more met location metadata checks: WasBredEgg
* Replace Console.Write* with Debug.Write*
There's no console output UI, so don't include them in release builds.
* Inline WasGiftEgg, WasEvent, and WasEventEgg logic
Adios legality tags that aren't entirely correct for the specific format. Just put the computations in EncounterFinder.
GetCanKnowMove should be checking for Smeargle knowing thousand arrows/waves.
GetNeededMoves should also return 1ka/1kw for needed moves, and then no encounters.
All uses of InvalidSketch are behind that method, so any future Smeargle modifications (like sketching a dummied move) will be checked (yay BDSP considerations).
