Added HandleAchievementTriggeredEvent to AchievementManager

HandleAchievementTriggeredEvent is an asynchronous method that processes an event and places a synchronous AwardAchievement call on the work queue. In the process, it also updates the unlock map and makes the ActivateDeactivateAchievement call to determine and adjust the achievement's current active state.
