bcat:u: Implement EnumerateDeliveryCacheDirectory

Browse source 
Basic implementation `EnumerateDeliveryCacheDirectory` call to `IDeliveryCacheStorageService` according to RE.  (close #622)
I've added some comments in the whole service for when we'll implement a real bcat implementation.
For now, all games who use it isn't playable because of GPU.
