Which issue does this PR close?
re #3407
Rationale for this change
Rationale is that I am always confused / have to remind myself what the various memory functions track. #3501 from @askoa (❤️ ) added a third so I felt it was time to document what was going on here better (with a diagram!)
What changes are included in this PR?
Add documentation about various memory functions on ArrayData
Are there any user-facing changes?
