Do not parcel legacy TextClassification fields

Browse Source 
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.

Bug: 78340399
Test: atest CtsViewTestCases:TextClassificationManagerTest
Test: atest FrameworksCoreTests:TextClassificationTest
Test: manual check with a TCS that only sets non-deprecated fields vs a
legacy TC client
