Update surface positions for animations earlier

When there is a new surface position of the InsetsSourceControl, the
leash position can updated either:

- during the insets animation (the surface position of the
  InsetsSourceControl used by the animation would be updated first), or
- via InsetsSourceConsumer#applyRequestedVisibilityAndPositionToControl
  if there is no running animation.

However, the surface position of the InsetsSourceControl used by the
animation was updated too late. If there is an animation running on the
InsetsAnimationThread (different from the main thread), it might update
the leash position based on the stale position.

This CL updates surface positions for animations before checking
InsetsController#hasSurfaceAnimation.
