allocator_api

The tracking issue for this feature is #32838

Sometimes you want the memory for one collection to use a different allocator than the memory for another collection. In this case, replacing the global allocator is not a workable option. Instead, you need to pass in an instance of an AllocRef to each collection for which you want a custom allocator.
