[WK2] calculate tiledBackingStoreVisibleRect including animation trajectory.

[Title] [WK2] calculate tiledBackingStoreVisibleRect including animation trajectory.
[Issue#] N_SE-25602
[Problem] TBS can not create tiles which is outside of keepRect while animation is running.
[Cause] during the animation, WebGraphicsLayer did not update itself's backing store by animation keyframes.
[Solution] unite the regions that the animation trajectory starts and ends.
