Fix UiTranslation for ListView.

There are 2 changes:
* When a view is scrapped, Autofill IDs in its subtree are reset. This
prevents flaky behavior like translating the wrong views when events are
ordered a certain way.
* Views that are being translated are marked as having transient state
since the system needs to attach the response to it later as well as
deliver UI Translation state changes to it.
