[ML] Add data drift detection workflow from Trained models to Data comparison view (#162853)

## Summary

This PR adds data drift detection workflow from Trained models to Data
comparison view. It also renames Data comparison to Data Drift.

**From the new map view in Trained model list:**

- Clicking on the index icon in the map view will give an option/action
to Analyze data drift

- If model has detected related indices, it will also give an option to
Analyze data drift in the Transform actions

**From the data comparison/drift page:**

- Default screen with list of available data views and saved search will
be shown

- But can also customize index patterns for the data sets to analyze.
Upon 'analyzing', a new data view will be created if needed (either
permanently or temporarily).

- If there exists a data view with exact combination of index patterns
and time field, it will use that data view
- If there exists a data view with the same index patterns but different
time field, it will create a new data view with name
`{referencePattern},{comparisonPattern}-{timeField}`
- If no data view exists that matches, it will create a new data view
with name `{referencePattern},{comparisonPattern}`


## For reviewers:
- **appex-sharedux**: [Small change in the exported type interface for
BaseSavedObjectFinder](https://github.com/elastic/kibana/pull/162853/files#diff-5e2e62df8aba5ac9445962bfa00eee933a386110d0a24dfe6ac0f300a796ccc3)
to correctly list `children` as an accepted prop. This prop which is
used for the `toolsRight`.
- **security-solution**: Renaming of `Data comparison` to `Data Drift`

## Tests:

### Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.

When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:

| Risk | Probability | Severity | Mitigation/Notes |

|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces&mdash;unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes&mdash;Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
