patch 8.2.3844: Vim9: no type error if assigning func(number) to func(string)

Problem:    Vim9: no type error if assigning a value with type func(number) to
            a variable of type func(string).
Solution:   Use check_type_maybe(): return MAYBE if a runtime type check is
            useful.  (issue #8492)
