Implement Prototype ability (#11249)

Prototype is a SpellAbilityType, for which alternate costs are permitted. It has a continuous effect that applies on the battlefield as well as a method to modify the spell on the stack. Permanents have an isPrototyped flag that copy effects can check explicitly (same brittle method as transformed permanents use; reworking copy effects to streamline them is a separate scope).

Many test cases have been added to confirm functionality (thanks to Zerris for additional test suggestions).
