Oddly enough, Emacs's current C code can't do that: the C code traverses
the whole menu, turns it into a new data-structure using the format
expected by the UI toolkit, and passes it to the toolkit.

It would be good to change that such that the conversion from Lisp
format to the toolkit format is done incrementally via callbacks, but
it's a longstanding limitation that nobody has felt like tackling yet.
