[core/file_sys] implement IApplicationFunctions::GetPseudoDeviceId; common PatchManager::GetNACP for base|updates (#4159)

a bit of refactoring so there's less code duplication...
probably a good idea to make it a lambda anyways
maybe this is why QLauncher didn't have proper DLCs and updates?

either way "GetPseudoDeviceId" is now implemented (still stubbed) with a proper hash instead of just 0
