Choose Token AI

Effects like Tireless Provider that does use `GenericChoice` to choose between two Token Scripts:
```
SVar:TrigTokenChoice:DB$ GenericChoice | Defined$ You | Choices$ Food,Treasure | SpellDescription$ Whenever a land enters the battlefield under your control, create a Food token or a Treasure token.
SVar:Food:DB$ Token | TokenAmount$ 1 | TokenScript$ c_a_food_sac | TokenOwner$ You | SpellDescription$ Food
SVar:Treasure:DB$ Token | TokenAmount$ 1 | TokenScript$ c_a_treasure_sac | TokenOwner$ You | SpellDescription$ Treasure
```

maybe should be somehow merged into Token Effect with a `ChooseToken` Parameter

But the Most important part is to add a logic for AI to choose which of the `TokenScript` is the most beneficial for the current situation.
Or maybe add an AI logic to make AI choose the more preferred one.

Or add AI logic to the Sub Abilities when to prefer them? (choose Food if life is low? If it can gain life?)

==
The current state is that AI will always choose the first one.
