Do not parcel legacy TextClassification fields

If we depend on legacyIntent, then TextClassifierService implementations
will have to always popuplate a deprecated field.
To avoid breaking legacy clients, the returned legacyOnClickListener should
represent the first pendingIntent (i.e. primary action) that was parcelled.

legacy TC client
