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.
