**Addresses:** elastic#202079

## Summary

This PR implement prebuilt rules import [test plan](https://github.com/elastic/kibana/blob/main/x-pack/solutions/security/plugins/security_solution/docs/testing/test_plans/detection_response/prebuilt_rules/prebuilt_rule_import.md).

Prior existing tests were superseded by the new ones.

## Discovered issues

It turned out that the current implementation behaves slightly differently than described the test plan. Failed test scenarios are skipped and the following tickets have been created for tracking

- elastic#223099
- elastic#223280
- elastic#223253

## Extra changes

Some diff like in `alert_threat_enrichments.cy.ts` has been caused by disabling errors swallowing upon rule creation. It's important to have tests properly preparing the testing environment to reduce chances of test dependencies and flakiness. In particular some prebuilt rules import test scenarios require custom rules to be created. Swallowing rule creation errors reduces tests coverage.

## Flaky test runner
