Fix: Terastallize Ogerpon and Terapagos with different Tera types

Terapagos

• Terapagos-Terastal can terastallize into other Tera types and transforms into Terapagos-Stellar.
• Teraform Zero activates but doesn’t deactivate the weather or terrain. Instead, it sends a failure message. Due to how overworld weather works in Generation IX, Teraform Zero will fail to protect from its effects.

Ogerpon

• Embody Aspect should not activate unless the user is Terastallized.
• Hacked Ogerpon-[form]-Tera forms should be allowed to Terastallize.
• Hacked Ogerpon forms will become whatever the Tera Type is for that Ogerpon.
• The game still softlocks if you try to Terastallize Ogerpon with a non-Grass/Fire/Rock/Water Tera Type.
• It will allow, for example, a Tera Water Ogerpon-Hearthflame holding Hearthflame Mask (Ogerpon-2) to Terastallize to Ogerpon-Wellspring-Tera (Ogerpon-5). Doing so will change Ogerpon to Water-type, but still give an Attack boost, and Ivy Cudgel will still be Fire-type.

I added the ruleTable.has('obtainablemisc') condition in the TeamValidator to allow players to use Ogerpon and Terapagos with different Tera Types in Hackmons. The client would also need to support changing Tera Types in the builder (at least for Hackmons).

ik you're still in draft, but shouldn't this be species.forceTeraType?

According to DaWoblefet

• Hacked Ogerpon-[form]-Tera forms will become whatever the Tera Type is for that Ogerpon.
• it will allow, for example, a Tera Water Ogerpon-Hearthflame (or Ogerpon-Hearthflame-Tera) holding Hearthflame Mask (Ogerpon-2) to Terastallize to Ogerpon-Wellspring-Tera (Ogerpon-5). Doing so will change Ogerpon to Water-type, but still give an Attack boost, and Ivy Cudgel will still be Fire-type.

Basically, if Ogerpon-Hearthflame Terastallizes into a Water type, its species becomes Ogerpon-Hearthflame-Tera, but its appearance changes to Ogerpon-Wellspring-Tera (and it becomes a Water type). In this case, the input of formChange would be Ogerpon-Hearthflame-Tera (to handle the ability and the type of Ivy Cudgel), but the details should be Ogerpon-Wellspring-Tera.

This is just a draft because I still have an open PR that will conflict with this (all the displayedSpeciesName logic would be moved to a separate function that handles the details), but I think I'll put it for review.
