Emit nbtree vacuum cycle id in nbtree xlog through FPIs

NBTree needs a vacuum cycle ID on pages of whom the split resulted in a new right page that is located before the original page, or who were split from such split pages in the current vacuum cycle. By WAL-logging the cycle_id and restoring it in recovery, we assure vacuum doesn't fail to clean up the earlier pages. During recovery, we extract the cycle ID from the original page if this page had an FPI, either directly (when the page was restored) or indirectly (from the record data). This fixes #9929
