Makes IAA good (Spawn more IAA, No more TC, Anti-tampering dust implant) (#19327)

Internal Affairs Agents now drop a special item on death. To get your kill reward as a syndicate, you must pick this item up and use it. Doing this spawns another Internal Affairs Agent.
Internal Affairs kill reward is now a random syndicate item instead of 5TC
Internal Affairs dusting implant now activates automatically if tampered with
Internal Affairs dusting implant is now automatically removed (safely) when the antag status is removed
