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`

801892b59e potential revisions for gible (#3462)
ddc6f414df caused it to be `<=` instead of `<`, but maybe the underlying issue was fixed a different way since all tests still pass with this reversion.

8f9de86347 Span-ify BreedInfo, saves 10bytes heap alloc
the Actual result still needs to leave the stack, so that has to be heap allocated.

2874f6fc69 Revise pichu volt tackle egg handling
Clean up ParseMovesWasEggPreRelearn as only EncounterEgg call into it, and no EncounterEgg has a special moves interface implemented.

50b15cd740 Use range/index
More in line with modernizing the codebase with latest c# syntax

improve web-qr decode speed slightly (no linq skiptake)
get money/coin mask without a temporary string (lol performance)

Relearn suggestions + Headbutt Slot Fix (#3190)
This change revises the logic for an Egg Move's RelearnMoves.

Removes a class that is no longer used
Passes the large value-passing struct byref via in keyword
Revises handling so that early-returned results from the MoveBreed processing are marked with their move source rather than leaving them unvisited.
The moveset processor uses depth search recursion, and returns false if the move that it is processing is not possible for the hatched moveset. If the depth search never reaches the check for base moves, all moves won't be marked for their origins, resulting in the result array not being accurate to use for suggestion purposes.

Yay multi-purpose logic (validation w/early returns & fixing needing fully processed data).

Add Breeding move ordering logic, and use in legality analysis (#3183)
* Initial bred moveset validation logic

Unpeel the inheritance via recursion and permitted moves

* Volt tackle considerations

* Optimize out empty slot skips

* Add tests, fix off-by-one's

* Require all base moves if empty slot in moveset

* Add test to prove failure per Anubis' provided test

* Tweak enum labels for easier debugging

When two enums share the same underlying value, the ToString/name of the value may be either of the two (or the last defined one, in my debugging). Just give it a separate magic value.

* Fix recursion oopsie

Also check for scenario where no-base-moves but not enough moves to push base moves out

* Add Crystal tutor checks

* Add specialized gen2 verification method

Game loops through father's moves and pushes in one iteration, rather than checking by type.

* Add another case with returning base move

* Add push-out requirement for re-added base moves

* Minor tweaks

Condense tests, fix another off-by-one noticed when creating tests

* Disallow inherited parent levelup moves

Disallow volt tackle on Gen2/R/S

* Split MoveBreed into generation specific classes

Gen2 behaves slightly different from Gen3/4, which behaves slightly different from Gen5... and Gen6 behaves differently too.

Add some xmldoc as the api is starting to solidify

* Add method overload that returns the parse

Verify that the parse order is as expected

* Add reordering suggestion logic

Try sorting first, then go nuclear with rebuilding.

* Return base moves if complete fail

* Set base moves when generating eggs, only.

* Use breed logic to check for egg ordering legality

Don't bother helping for split-breed species
