[Security Solution][Endpoint] Migration for artifacts in support of space awareness (#222700)

## Summary

PR adds migration of Response Actions and Artifacts when the space
awareness feature flag is enabled. Changes include:

- New saved object type (`security:reference-data`) to keep internal
data/information used by security solution. Currently being used to keep
migration state for both the Artifacts and Response actions migrations
- Two records will be populated in this new saved object related to the
migration being introduced here:
- ID: `SPACE-AWARENESS-ARTIFACT-MIGRATION` - keeps state information
about migration of Artifacts (see below for example)
- ID: `SPACE-AWARENESS-RESPONSE-ACTIONS-MIGRATION` - keeps state
information about migration of response actions (see below for example)
- NOTE: my goal was to also introduce a `client` for working with
internal reference data, but due to timing constraints, that will be
done at a later time
- Adds migration for Endpoint artifacts (Trusted applications, Event
filters, Blocklists, Host isolation exceptions and Endpoint exceptions)
to add the `spaceOwnerId:default` to all artifact records
- Adds migration for Response Action Requests (both Elastic Defend and
external EDRs) to populate `originSpaceId` as well `agent.policy.*`
fields.
- NOTE: when populating the `agent.policy.*` data, it may be possible
that the agent that the response action was sent to is no longer
available (ex. unenrolled). In such cases, the migration will populate
any field that it is not able to retrieve information for with the text
`MIGRATION:NOT-FOUND`


> [!IMPORTANT]
> The migration currently assumes that the `9.1.0` endpoint package is
already installed, which will not be the case with a real migration. To
test this PR, you should start a 9.1 stack with the feature flags
disabled... Install the `9.1.0` endpoint package, and then enable the
feature flags.
> We will be working on a solution handling this data condition in a
subsequent PR
