Introduce AActor::TakeInventory, which unifies DoTakeInv from ACS and DoTakeInventory from Decorate, and AInventory::DepleteOrDestroy, which is extracted from the DoTakeInv core function, and use both where they're needed. I don't know if the differences between DoTakeInv and DoTakeInventory were intentional, so I kept both behaviors.
