This PR Implement `EndFreeCommunication` (checked by RE). Nothing more.

Closes #2420

* aoc/am: Cleanup aoc service and stub am calls

This PR implement aoc call `GetAddOnContentListChangedEventWithProcessId` (Closes #2408) and `CreateContentsServiceManager`. Additionnally, a big cleanup (checked by RE on latest firmware) is made on the whole service. I've added `CountAddOnContent`, `ListAddOnContent` and `GetAddonContentBaseId` for games which require version `1.0.0-6.2.0` too.

Am service call `ReportUserIsActive` is stubbed (checked by RE, closes #2413).

Since some logic in the service (aoc) which handle the DLCs has been changed, it could be nice to have some testing to be sure there is no regression.
