[Console Monaco Migration] Fix issue with different themes (#180321)

Fixes #180218

## Summary

This PR fixes the highlighting issue in the Monaco editor that is caused
when using a theme in the output panel that is different from the theme
in the editor. This fix is implemented by unifying the themes for both
editors into one.

The PR also fixes the issue with Console theme overwriting theme in
other code editors (e.g. embeddable Console in the index detail tabs) by
reusing the `euiTheme`.

Note: This solution changes some of the original highlighting colors in
Console (e.g. comments were green and now they are grey, background
color is also different now). We might be able to fix the text colors by
specifying unique token names in the Console language (e.g. using
`consoleComment` instead of `comment` token name). cc: @yuliacech

### 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) |
