* Added Gen2 italian items text
* Italian translation text_ItemsG2_it.txt
* Translated MessageStrings_it.txt and improved some other italian messages/strings for better comprehension.
* Some tweaks
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
* 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.
Future-proofing. We know that Hisuian Zoroark is in SV, as well as Petilil, so if Hisuian Lilligant is also present, we need to not show Lady Lilligant in the form dropdown for those games.
Also only show Primal Kyogre/Groudon for Gens 6/7 (can be revised later if they come back in SV).
Old jank that makes stuff less obvious to follow. Very very few people want out-of-bounds levels, even in HaX.
We have the batch editor to mutate these properties if it is really desired; same as Status condition/etc.
Don't trigger event calls if sanitized value is same as input.
Update PKMEditor.cs
ShowdownSet: Lessen allocation
MoveTutor: Remove boxing by calling the generic method instead of object method
Xoro8b: Add more xmldoc, use positive constant instead of inverse negative for parity
StadiumUtil: Use built-in endianness reversal methods
