Fix SacrificeTargetCost and SacrificeAllCost activator checks (#12809)

* Fix Tergrid's Lantern and add test

* Remove custom effect, fix SacrificeTargetCost to avoid checking for activated abilities and sidestepping the controllerID

* Add test to verify change to SacrificeTargetCost

* Add special action test

* Fix canPay check for SacrificeTargetCost

* Remove activated ability check in SacrificeAllCost

* Remove cost-specific activator checks for special actions, as they are redundant

* add null check for game.getPlayer
