Combine RecentsViewStateController with base class

- BaseRecentsViewStateController is only inherited by RecentsViewStateController, remove the base class to simplify code - Also converted RecentsViewStateController to Kotlin and remove a bunch of warnings Fix: 387267938 Test: presubmit and manual Flag: EXEMPT refactor Change-Id: I18e9c2b186a64a0af39230cb41e3b3f4949107d5
