vim-patch:8.2.1047: Vim9: script cannot use line continuation like :def function

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.

https://github.com/vim/vim/commit/5409f5d8c95007216ae1190565a7a8ee9ebd7100

Omit source_nextline() and eval_next_non_blank(): Vim9 script only.
