settings_ui: Handle enums with fields (#37945)

Closes #ISSUE

Adds handling for Enums with fields (i.e. not `enum Foo { Yes, No }`) in
Settings UI. Accomplished by creating default values for each element
with fields (in the derive macro), and rendering a toggle button group
with a button for each variant where switching the active variant sets
the value in the settings JSON to the default for the new active
variant.

Release Notes:

- N/A *or* Added/Fixed/Improved ...
