This change is another minor step towards removing `AK::String` from the Kernel. Instead of dynamically allocating the storage_name we can instead allocate it via a KString in the factory for each device, and then push the device name down into the StorageDevice base class. We don't have a way of doing `AK::String::formatted(..)` with a KString at the moment, so cleaning that up will be left for a later day.
