In this pull request I've changed a ton of method signatures to reflect the more-narrow types of Species, Move# and Form; additionally, I've narrowed other large collections that stored lists of species / permitted values, and reworked them to be more performant with the latest API spaghetti that PKHeX provides. Roamer met locations, usually in a range of [max-min]<64, can be quickly checked using a bitflag operation on a UInt64. Other collections (like "Is this from Colosseum or XD") were eliminated -- shadow state is not transferred COLO<->XD, so having a Shadow ID or matching the met location from a gift/wild encounter is a sufficient check for "originated in XD".
* Rewrite ribbon verification
* Explicitly verifies all ribbons instead of chained iterators.
* Verifies using only the stack, using `struct` and `Span<T>`. No allocation on heap, or `IEnumerable` iterators.
* Verifies all egg ribbons using a separate method, explicitly implemented. No reflection overhead.
* Separates each ribbon interface to separate `static` classes. Easier to identify code needing change on new game update.
* Extracted logic for specific ribbons. Can easily revise complicated ribbon's acquisition rules.
* Simplifies GiveAll/RemoveAll legal ribbon mutations. No reflection overhead, and no allocation.
* Can be expanded in the future if we need to track conditions for ribbon acquisition (was Sinnoh Champ received in BDSP or Gen4?)
End result is a more performant implementation and easier to maintain & reuse logic.
