If we are discarding the whole resource, we don't care about previous contents, and the resource storage is now unused, either because we have created new resource storage, or because we have waited for the existing resource storage to become unused, or because the transfer is unsynchronized. In the last two cases this commit marks the storage as uninitialized, but only if the resource is not host writable (in which case we can't clear the valid range, since that would result in missed readbacks in future transfers). In the first case, when the whole resource discard involves a reallocation, the reallocation and subsequent rebinding already update the valid buffer range appropriately.
