patch 8.2.4390: Vim9: list from declaration with inferred type not set

Browse Source 
Problem:    Vim9: list from declaration with inferred type does not set the
            type on the value.
Solution:   When inferring the type in a variable declaration also set the
            type of the list or dictionary. (closes #9705)  Do not set the
            type when the member is "any".
