[Security Solution] [AI Assistant] security assistant content referen…

…ces tour (elastic#208775)

## Summary
Follow up to : elastic#206683

This PR adds a tour that tells the user how to toggle citations on and
off and how to show and hide anonymized values.

### How to test:
- Enable feature flag: 
```yaml
# kibana.dev.yml
xpack.securitySolution.enableExperimental: ['contentReferencesEnabled']
```
- Launch the security AI assistant
- Now we need to get the assistant to reply with a message that contains
either anonymized values or citations. This is what triggers the tour.
To do this ask it a question about one of your KB documents or an alert
that contains anonymized properties or returns a citation.
- Once the assistant stream ends, the tour should appear 1 second later
(unless the knowledge base tour is open).

The tour will only appear one time per browser. To make it appear again,
clear the key
`elasticAssistant.anonymizedValuesAndCitationsTourCompleted` from local
storage.
