Disallow single file checkpoint from MDB server

      • Some WiredTiger operations require exclusive handles on objects to succeed (verify, alter, salvage, etc.), which requires no dirty data in the cache before an exclusive handle is granted.
      • Historic WiredTiger releases would individually checkpoint these objects, outside of a database-wide checkpoint, so exclusive access could be granted.
      • Checkpointing objects outside of a database-wide checkpoint potentially leads to data inconsistencies (see WT-8695), so checkpointing single objects was made an error.
      • That led to MDB Server test fallout, see SERVER-63605 and SERVER-64026.
      • Part of the WT-8695 change was reverted, allowing single object checkpoints in MongoDB Server builds, while leaving them an error in standalone builds (see WT-8883).
      • When SERVER-64026 is closed, single object checkpoints should be disallowed in all builds.
