patch 8.2.1459: Vim9: declaring script var in script does not infer the type

    patch 8.2.1459: Vim9: declaring script var in script does not infer the type

    Problem:    Vim9: declaring ascript variable at the script level does not
                infer the type.
    Solution:   Get the type from the value. (closes #6716)
