[ExtraHop][Qualys GAV] - Fix Cannot execute ILM policy delete step (#132387)

This PR focuses on the short term solution which add the logs-extrahop.investigation-* and logs-qualys_gav.asset-* indices under the kibana_system role with deletion privileges to prevent a failed deletion error when the index enters the deletion phase for the ILM lifecycle, in upcoming PRs.
