[adapters] Delta output: enable checkpoints.

The Delta output connector did not create periodic checkpoints.

While this is in itself problematic, it also meant that the connector
became slow over time, due to this delta-rs bug, which causes the
`update_incremental` function to scan the entire transaction log on
every commit:
delta-io/delta-kernel-rs#2103.

This commit:
- Introduces the `checkpoint_interval` option, which tells
  the connector to configure checkpoint interval when creating
  the table.
- Creates a CommitBuilder that is actually setup to create
  checkpoints.

Without this fix the time to create a trivial delta commit increases from
1.5s to 6s after ~1000 commits. With the fix it remains constant at
~2s.
