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)
