[Serverless][Advanced Settings] Add validations on user input (#170234)
Addresses https://github.com/elastic/kibana/issues/168684

## Summary

This PR adds validations of the user input for a some of the uiSettings
(see https://github.com/elastic/kibana/issues/168684) based on the
`schema` that is provided in the setting definitions. We do this by
exposing a `validateValue` API from the uiSettings browser-side client,
which calls an internal validate route to the server. Then
`validateValue` is called in the `onChange` handlers of the setting
input fields, utilising `debounce` to reduce the number of requests to
the server.

Note: One of the validation requirements is for validating that the
`defaultIndex` setting value is an existing data view. This is a more
complicated validation and will be addressed in a separate PR.

### How to test
**Testing the validations in serverless:**
1. Start Es with `yarn es serverless` and Kibana with `yarn
serverless-{es/oblt/security}`
2. Go to Management -> Advanced settings
3. Verify that the UI provides correct validation error messages for
[the settings that require
validation](https://github.com/elastic/kibana/issues/168684).

**Verify that self-managed Kibana is not affected:**
There should be no validations in self-managed Kibana and setting an
invalid value for an advanced setting should be allowed and shouldn't
cause any errors.

@elastic/kibana-core team, I know you're no longer code owners of the
uiSettings service, but any feedback on those changes will be highly
appreciated. 🙏

### 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) |

as work on serverless picks up we will add config values to these files that define how Kibana will run in "serverless" modes. To start Kibana locally with this configuration, pass --serverless={mode} or run yarn serverless-{mode}

valid modes are currently: es, oblt, and security

configuration is applied in the following order, later values override

  1. serverless.yml (serverless configs go first)
  2. serverless.{mode}.yml (serverless configs go first)
  3. base config, in this preference order:
  • my-config.yml(s) (set by --config)
  • env-config.yml (described by env.KBN_CONFIG_PATHS)
  • kibana.yml (default @ env.KBN_PATH_CONF/kibana.yml)
  1. kibana.dev.yml
  2. serverless.dev.yml
  3. serverless.{mode}.dev.yml
