TalkBack was not announcing position information (e.g. '1 of 3') for radio buttons and checkboxes in expanded ChoiceSet inputs. This is because RadioGroup and LinearLayout-based CheckBox containers do not automatically provide collection semantics to TalkBack. Added CollectionInfo on the parent containers and CollectionItemInfo on each child item via AccessibilityDelegateCompat, so TalkBack now announces items like: 'Red, radio button, 1 of 3, not checked'. Fixes microsoft#89

Summary
TalkBack was not announcing position information (e.g. "1 of 3") for radio buttons and checkboxes in expanded ChoiceSet inputs. This is because the container views (ValidatedCheckBoxLayout extending LinearLayout, and ValidatedRadioGroup) do not automatically provide collection semantics that TalkBack needs for position announcements.
