Operational swing-store artifact level (#9391)

closes: #9388

## Description

Switch from `replay` to `operational` for state-sync export/restore,
genesis export/import, and as the default for cosmic-swingset's
export/import of kernel DB command line tool.

Drive by change of the default chain home directory for the
import/export tool (this location was effectively changed a couple year
ago but not consistently in the rest of the SDK).

### Security Considerations

If all nodes prune historical "replay" artifacts, we lose the ability to
perform replay based upgrades in the future. We expect archive nodes to
not manually prune their DB in this way.

### Scaling Considerations

This should have no impact on performance right now. In the future, when
exporting the IAVL data is not as slow, this would reduce the time it
takes for state-sync snapshots to be created.

### Documentation Considerations

Should communicate this change with validators

### Testing Considerations

Covered by existing integration tests.

### Upgrade Considerations
