Refactor nbtree high key truncation. Simplify _bt_truncate(), the routine that generates truncated leaf page high keys. Remove a micro-optimization that avoided a second palloc0() call (this was used when a heap TID was needed in the final pivot tuple, though only when the index happened to not be an INCLUDE index).
Removing this dubious micro-optimization allows _bt_truncate() to use the index_truncate_tuple() indextuple.c utility routine in all cases. This was already the common case. This commit is a HEAD-only follow up to bugfix commit 4b42a899.
