* pgsql: Use atomic access for SlruShared->latest_page_number

Use atomic access for SlruShared->latest_page_number
The new concurrency model proposed for slru.c to improve performance
does not include any single lock that would coordinate processes
doing concurrent reads/writes on SlruShared->latest_page_number.
We can instead use atomic reads and writes for that variable.
