[Pivot Table] Add descendant_slice_by_stack dynamic table
Added enum types to descendant generator and added
descendant_slice_by_stack operator that takes a stack_id and finds all
slice ids that have that stack_id, then finds all descendants of all the
slice ids similarly to descendant_slice.
Next Step: Add stack expansion to pivot table.
