feat: add HOLDOUT_TYPEDAUDIENCE_HOLDOUT to ValidProjectConfigV4

- Added public constant HOLDOUT_TYPEDAUDIENCE_HOLDOUT to class ValidProjectConfigV4
- Updated feature flag constants to public static in class ValidProjectConfigV4
- Updated holdout constants to public static in class ValidProjectConfigV4
- Created unit test userMeetsHoldoutAudienceConditions in DecisionServiceTest
