[scudo][standalone] Use BatchClassId in drain rather than 0

D99763 fixed `SizeClassAllocatorLocalCache::drain` but with the
assumption that `BatchClassId` is 0 - which is currently true. I would
rather not make the assumption so that if we ever change the ID of
the batch class, the loop would still work. Since `BatchClassId` is
used more often in `local_cache.h`, introduce a constant so that we
don't have to specify `SizeClassMap::` every time.
