TDFC cleanup follow up

[Jmlundeen]

This is some additional cleanup for the transforming double faced card rework.

• remove secondSideCardClazz used by old transforming cards
• remove TransformAbility since not needed anymore
• cleanup TODO items
  • moved VALUE_KEY_ENTER_TRANSFORMED to TransformingDoubleFacedCard
  • removed transform validation in Player.moveCards and kept in ZonesHandler. Doesn't seem necessary to have redundant check.
  • removed old transform card check from Mycosynth Lattice and Painter's Servant
  • removed old transform related code from PermanantCard init
  • remove ignoreTransformEffect flag from SpellTransformedAbility (temporary flag to separate from old transform implementation)
  • remove instanceof DoubleFacedCardHalf check from CardImpl copy constructor; DFC will still use the field, instance check is currently just to differentiate between old Transforming logic

part of #14099

looks like original card has some typos... must be 1 effect and 1 filter, not 2:

[Jmlundeen]

yeah it needs a filter like this, but the types are incompatible since AnotherPredicate uses the ObjectSourcePlayer

The actual card is silver bordered and the existing implementation is bogus anyway because it isn't something that can be well defined in the rules. So not important for this PR.

I don't see any issues
