Animation Modifier : Fix Modifier on Skeleton Transfered the ownership of 'PreviouslyAppliedModifier' from an animation modifier instance to the animation sequence being applied. This solved the following issue: - Modifier on Skeleton cause USkeleton dirtied everytime the modifier is applied to an animation sequence. - Modifier on Skeleton cannot be re-apply or reverted correctly. - CanRevert & OutOfDate status for Modifier on Skeleton was not reflect the true status of all animation sequences referencing that skeleton. - CurrentAnimSequence/CurrentSkeleton was not set on OnRevert() - IAnimationDataController::FScopedBracket was not open on OnRevert() before re-apply modifier - Stateful animation modifier can now be reverted correctly (Applied modifier instance is nolonger reverted after OnApply call) #preflight 63775e0ff514e1ded99ef095 [CL 23191977 by Jurre deBaare in ue5-main branch]
