Add explanatory comment to prune_freeze_setup() heap_page_prune_and_freeze() fills in PruneState->deadoffsets, the array of OffsetNumbers of dead tuples. It is returned to the caller in the PruneFreezeResult. To avoid having two copies of the array, the PruneState saves only a pointer to the array. This was a bit unusual and confusing, so add a clarifying comment.
