I think here we should just be honest and admit that C enums and Java enums don't have much in common, except for the use of the word `enum`.

(note -- this does NOT mean that other, more specialized, code generators could not model C enums as Java enums. Perhaps in some code bases that makes total sense. But jextract is intended to provide reliable bindings for _all_ C headers -- which sort of restricts the kind of tricks we can play)
