fix concurrency issues with the LFC
...
- Add another locking hash table to track which cached pages are currently being
modified, by smgrwrite() or smgrread() or by prefetch.
- Use single-value Leaf pages in the art tree. That seems simpler after all,
and it eliminates some corner cases where a Value needed to be cloned, which
made it tricky to use atomics or other interior mutability on the Values
