Fix/constraint value wrapping (#9873)

Changes how constraint values are treated and wrapped.

Previously, they would have their own column and fill it up:

Then we changed it to always being on the next line below certain
widths:

But that would also cause it to break even if there was no need for it.
This iteration instead uses display `contents` on the value lists to let
them be handled by the flex flow of the containing element. This allows
them to only wrap when necessary.

Of course, if they don't need to wrap, they don't:

/>


This loom video shows how it folds in the most complex scenario, with
all elements being visible and within bounds down to about 300px:
