Move commonly used context into PruneState and simplify helpers heap_page_prune_and_freeze() and many of its helpers use the heap buffer, block number, and page. Other helpers took the heap page and didn't use it. Initializing these values once during prune_freeze_setup() simplifies the helpers' interfaces and avoids any repeated calls to BufferGetBlockNumber() and BufferGetPage().
While updating PruneState, also reorganize its fields to make the layout and member documentation more consistent.
