[ES|QL] Add ECS information to the editor hint & prioritize fields based on ECS information on the editor (#187922)

## Summary

Closes https://github.com/elastic/kibana/issues/181036. This PR adds ECS
information to the editor hint & prioritizes fields based on ECS
information on the editor. The logic involves:

1) Identify if dataset has ecs fields (e.g. column contains ecs.version)
2) If yes, check which fields have ecs info using [fieldsMetadata
client](https://github.com/elastic/kibana/issues/181036#issuecomment-2149134909)
3) Push fields with ecs info up to the top of the list of suggestions
and order these fields alphabetically. These pushed fields have "1D"
sort text.
4) Show the rest of the fields without ecs decription at the bottom,
order these fields alphabetically.

**Note for reviewers**: 
- When fetching fields metadata, if there are many fields, we are
breaking down into multiple requests (250 fields/request) to avoid
payload too large.

### 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—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—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) |
