Avoid sending IME insets position in old rotation to client

IME token surface is hidden by reusing AsyncRotationController to
avoid showing intermediate state when running app transition with
rotation change. But it is not the accepted window type for
async rotation, so it can be excluded from freezing position.

This prevents the case if the client InsetsAnimationControlImpl
is late to call updateSurfacePosition by the old rotation after
server side updated to new position.
