NewPanelEdit: Add unified UI to queries and transformations (#23478)

* Do not use pointer cursor on icon by default

* Allow items alignment in the HorizontalGroup layout

* Add util for rendering components based on their type (element or function)

* Components for rendering query and transformation rows in a unified way

* Apply new UI fo query and transformation rows

* Add some tests

* Minor fix for scroll area
