Enforce TaskFragmentOrganizer can only manipulate organized TF

When TaskFragmentOrganizer apply a WCT using TaskFragment token, we
should also enforce that the TaskFragment is organized by the caller,
because when an app is embedded by another app, the embedee may be
able to get the fragment token from
ActivityClientRecord#mInitialTaskFragmentToken.

Also remove check for TYPE_REORDER because it is currently only
supported for Task, and we need to re-evaluate cross-process embedding
overlay if we want to allow reorder.
