DO NOT MERGE: Update ActivityRecordInputSink using the pending transaction

In some cases where finishTransition happens before the pending
transaction is applied, we can end up with a stale state. Subsequent
prepareSurfaces does not fix the issue because the InputWindowHandle is
only applied on changes.

Fix the race by only using pending transactions to apply
ActivityRecordInputSink state changes.
