patch 8.2.4053: Vim9: autoload mechanism doesn't fully work yet

Browse Source 
Problem:    Vim9: autoload mechanism doesn't fully work yet.
Solution:   Define functions and variables with their autoload name, add the
            prefix when calling a function, find the variable in the table of
            script variables.
