Doc: Refer to line pointers as item identifiers.
An upcoming HEAD-only patch will standardize the terminology around ItemIdData variables/line pointers, ending the practice of referring to them as "item pointers". Make the "Database Page Layout" docs consistent with the new policy. The term "item identifier" is already used in the same section, so stick with that. Discussion: https://postgr.es/m/CAH2-Wz=c=MZQjUzde3o9+2PLAPuHTpVZPPdYxN=E4ndQ2--8ew@mail.gmail.com Backpatch: All supported branches.
