patch 8.2.1047: Vim9: script cannot use line continuation like :def functionv8.2.1047

Problem:    Vim9: script cannot use line continuation like in a :def function.
Solution:   Pass the getline function pointer to the eval() functions.  Use it
            for addition and multiplication operators.
