[Character] Convert Load/Update of Character Alternate Currencies to Repositories (#3856)

- Convert `LoadAltCurrencyValues` and `UpdateAltCurrencyValue` to repositories.
- Cleanup some other code and logic as well.
- Add `AlternateCurrencyMode` namespace for `AltCurrencyPopulate_Struct` opcode magic numbers.
