Clean up effects that move cards corresponding to a permanent that left the battlefield

Followup from #14900 . Previous work #14919 , #14931. There are likely some remaining custom effects that don't properly account for the fact that a permanent may have mutated cards.

Things to consider for new and reworked implementations:
* Effects moving cards must iterate through all targets, not just the first
* Triggered abilities need to set target pointer for such use cases to fixed targets and use an effect that moves a target, not an effect that moves source/enchanted
* Use `CardUtil::getAllCardsFromPermanentLeftBattlefield` whenever you need to do something with a card that left the battlefield

Incomplete list of effects to check:
* [ ] "when this dies, return it to the battlefield (tapped and) transformed" [Scryfall search for 10 cards](https://scryfall.com/search?q=o%3A%2Fwhen+%7E+dies%2C+return+it+to+the+battlefield+%28tapped+and+%29%3Ftransformed%2F&unique=cards&as=grid&order=name)
* [ ] Adarkar Valkyrie and other cards using WhenTargetDiesDelayedTriggeredAbility
* [ ] Athreos, Shroud-Veiled
* [ ] ReturnToHandAttachedEffect (example bugged: Demonic Vigor; compare fixed: False Demise)
* [ ] Gift of Immortality (weird one)
* [ ] Lim-Dul the Necromancer
* [ ] Magnanimous Magistrate
* [ ] Necroskitter
* [ ] Meathook Massacre II
* [ ] Puppet Master
* [ ] DealtDamageAndDiedTriggeredAbility
* [ ] DealtDamageAttachedAndDiedTriggeredAbility
* [ ] Valkyrie's Call
* [ ] Vraska, the Silencer
* [ ] ReturnMORToBattlefieldUnderOwnerControlWithCounterEffect

For any reworks of custom card effects, consider if it can be accomplished with common classes.
