patch 8.2.3822: leaking memory in map() and filter(), no string in Vim9

Browse Source 
Problem:    Leaking memory in map() and filter(), cannot use a string argument
            in Vim9 script.
Solution:   Fix the leak, adjust the argument check, also run the tests as
            Vim9 script. (Yegappan Lakshmanan, closes #9354)
