patch 8.2.4573: a nested function is compiled for debugging without context

Problem:    A nested function (closure) is compiled for debugging without
            context.
Solution:   Check if a nested function is marked for debugging before
            compiling it.  Give an error when trying to compile a closure
            without its context. (closes #9951)
