NewPanelEditor: Thresholds v2 (#22232)

* initial wip

* Progress on new threshold design

* Testing radio button group for mode option

* Starting to come together

* Fixed percent mode

* Full width radio groups

* Minor tweaks, cursor to trash icon and hover state

* fixed unit tests

* Fixed storybook

* re-ordering fields

* Updated snapshot

* Make it consistent, add vs create
