Gen6 can get the memory on those who did not participate by being in the party with other participants.
This includes those who cannot enter into the Maison; having memory and no ribbon is entirely legal.
PKHeX needs the exact moveset rather than a "permit this extra move" because our recent logic improvements check for strict moveset matching when it is still an egg.
Closes#3577 thanks @wararjey !
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".
Disallow max moves from Sketch
Hide dmax moves from legal dropdown lists
Pass ushort for moves for validating memories
Internal class for move pp (hide empty class from dll users)
Fix RibbonVerifier4 not checking gen4 contest ribbons correctly
Split IRibbonCommon6 to have memory ribbons separate, as they are not implemented in mystery gifts. Also, we can add the boolean flags to the interface, and check that the boolean is set if count is nonzero.
Fix adding ribbons to Gen8 gift templates
Improve Gen8 template ribbon fetch (no closure, faster IndexOf)
`Moveset` struct stores 4 moves, and exposes methods to interact with a moveset.
`IndividualValueSet` stores a 6 IV template (signed).
Performance impact:
* Less allocating on the heap: Moves - (8 bytes member ptr, 20 bytes heap->8 bytes member)
* Less allocating on the heap: IVs - (8 bytes member ptr, 28 bytes heap->8 bytes member)
* No heap pointers, no need to jump to grab data.
* Easy to inline logic for checking if moves are present (no linq usage with temporary collections).
End result is faster ctor times, less memory used, faster program.
