Fix translation doesn't work on ViewGroup

The system will add requested view reference into cache but it is
possible the requested translation view is a viewgroup, we don't add
this into view reference list that cause the translation doesn't work
on ViewGroup.

Bug: 200233857
Test: atest CtsTranslationTestCases
Test: manual. Use a sample code to request translation for a
viewgroup and make sure it is added into view reference list.
Test: manual verify with issue client app, it works.
