This really irks me: getting notational elements to typeset in markup
currently means putting everything together by hand.

We do have \score inside of markup but it is a heavy-handed solution
requiring iteration of a music expression and hand-removing time
signatures, staff lines, clefs and so on.

We could simplify this process by providing an alternative output
definition that kills all such elements and/or possibly a NullStaff
context definition (where you can, when necessary, add back some output
elements by reverting the \omit statements from the NullStaff
definition).

But I feel that some intermediate layer not requiring iterations at all
(but maybe still supporting Grobs?) might do a better job.
