Stops hiding a11y services with the same package+label as an activity in shortcut logic.

Root Cause: We change the logic in Accessibility Settings to show all a11y services and activities,
hand over to developer to judge whether they want to show service type and activity type at the same
time.

Solution: Change the logic to show all a11y services and a11y activities in shortcut logic
