[Observability] Create observability-specific setting for excluding d…

…ata tiers from queries (elastic#192570) part of [elastic#190559](elastic#190559) ## Summary This PR introduces a new `Advanced Settings` under `Observabilty` to provide a way of configuring the exclusion of indices in the `data_cold` and/or `data_frozen` tiers from queries. The change will help to address issues encountered in O11y, most specifically in APM, and could also affect Infra and other features, with unbounded queries targeting the frozen tier. ### For reviewers This PR replaces elastic#192276 --------- Co-authored-by: Elastic Machine <[email protected]> (cherry picked from commit f029f80)
