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
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).
For BigEndian we don't have to invert the array access if we just iterate backwards :)
Fix xmldoc for gen1 trades ampersand
Add xmldoc for enc trade classes
No functional change.
hovering would grab ILocation, which didn't use the flexible met location fetch.
Just repoint stuff and have it as a virtual call, since most of these are fixed values, there's no point increasing the size of the classes besides those for gen4.
* Exploration: rework ability criteria to ability numbers desired
* Sync remaining changes
* Update EncounterCriteria.cs
* Add xmldoc
* Improve speed of IsDualGender check
* More xmldoc updates
Should be doing this on main but meh, this branch is gonna get merged later
* Fix typo
* Update WC7.cs
* Update PersonalInfo.cs
