vim-patch:8.2.1110: Vim9: line continuation does not work in function arguments

Problem:    Vim9: line continuation does not work in function arguments.
Solution:   Pass "evalarg" to get_func_tv().  Fix seeing double quoted string
            as comment.

https://github.com/vim/vim/commit/e6b5324e3a3d354363f3c48e784c42ce3e77453f

Omit skipwhite_and_linebreak_keep_string(): Vim9 script only.
