Update corner radius/shadow radius/box shadow only on transition-driven callback

This CL synchronizes updating some surface properties (e.g., corner
radius) with the transition animation.
Otherwise, due to non-transition callbacks (e.g., onTaskInfoChanged) the
property update can overtake the transition animation, which results in
flickering.
Unlike crop/position/visibility, these properties need to be set by
WindowDecor so we can’t consolidate it with the existing similar flag
`mSetTaskVisibilityPositionAndCrop`.
