Alerting: Prevents creating alerts from unsupported queries (#19250)

* Refactor: Makes PanelEditor use state and shows validation message on AlerTab

* Refactor: Makes validation message nicer looking

* Refactor: Changes imports

* Refactor: Removes conditional props

* Refactor: Changes after feedback from PR review

* Refactor: Removes unused action
