account/ns: Implement 13.0.0+ service calls (#2820)

This PR implements/stubs some missing calls introduced in recent firmware (13.0.0).

- `acc:u0 InitializeApplicationInfoV2` needed by ACNH.
- `aoc:u NotifyMountAddOnContent/NotifyUnmountAddOnContent/CheckAddOnContentMountStatus` checked by RE. Needed by ACNH.
- `IPurchaseEventManager PopPurchasedProductInfo` needed by Dying Light.

Now ACNH 2.0 update is fully playable, and Dying Light can boot further:
