[Console] Add Console parser to kbn/monaco (#177194)

## Summary

Related meta [issue](https://github.com/elastic/kibana/issues/176926) 

This PR adds the parser used by Ace in Console to the Console language
definition in `kbn/monaco`.
Changes introduced by this PR: 
- Copy the code for `'sense_editor/mode/worker_parser'` from the file
`src/plugins/console/public/application/models/legacy_core_editor/mode/worker/worker.js`
into the `kbn/monaco` package
- Move the code for the webworker from the `xjson` folder in
`kbn/monaco` to a shared folder `ace_migration`
- Register the parser worker for the Console language in `kbn/monaco`

### How to test
#### Test the parser in Console
1. Add `console.dev.enableMonaco: true` to kibana.dev.yml
2. Open Dev Tools Console and try to type a valid request, check that
there are no red markers in the editor
3. Type an invalid request and check that there are red markers in the
editor

#### Test that `xjson` language parser still works
1. Navigate to Ingest pipelines and click the "create from csv" button
2. Load a valid csv file, for example this
[one](https://github.com/kgeller/ecs-mapper/blob/master/example/mapping.csv)
3. In the editor that now display a valid json, try changing the value
and check that red markers appear for invalid json

### Screenshots

### 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) |
