Refactoring: Move Source (Legality) (#3560)
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

File scoped namespaces (#3529)
[Language Reference](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/proposals/csharp-10.0/file-scoped-namespaces)

Updates all the files, one less level of indentation.

Some small changes were made to API surfaces, renaming `PKM pkm` -> `PKM pk`, and `LegalityAnalysis.pkm` -> `LegalityAnalysis.Entity`

436588eb10 Replace é->e for code symbols
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.

d54a9ba3a9 Fix mg8 partially restricted language check
Recipient language fetching a value of 0 will now be permitted to yield the recipient's language. Earlier logic in the method would check if any other language maps to the recipient language

86814d014d Fix recog of Home fixed PID shinies
Not to be confused with Home fixed PID antishinies
WC8 is the only format to have fixed shinies, but let's copy the logic to WB8 and WA8 if they're ever added in the future.

Fix mgdb display filtering for SWSH & PLA (swapped oops)

Closes #3511

HOME 2.0.0: Handle conversion behavior & restrictions (#3506)
* 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.

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 (#3483)
* 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.

93255efcb8 Disassociate Shiny enum from WC6 PIDType (#3461)
Have `Shiny.Random` be `0`, so we can skip init on this field for EncounterStatic. Plus makes it a little less brittle for future expansion if shiny qualities change.
