Consolidated the existing logic from OtherActivityInputConsumer
into AbsSwipeUpHandler#getLaunchIntent() directly, so it is
inherited for both AbsSwipeUpHandler and OverviewCommandHelper.
This change means we stop starting RecentsActivity when pressing
the overview button. (And, in turn, this means we no longer use
FallbackTaskbarUIController<RecentsActivity>.)
Bug: 401382430
Test: Open an app, press Overview button, dump TaskbarUIController
