Have separate sampler per heap.

This will allow us to have separate sampling rates per heap (e.g. ART
Allocation Tracking could be higher volume, so we want a higher
interval).  This also is necessary if we want to allow clients to report
samples rather than allocations for their heap, because that will cause
that heap to have a separate (implicit) sampler, while all the others
share one.
