An attribute set containing global variable values
for storing vim variables as early as possible. If
populated, this option will set vim variables in the
built luaConfigRC as the first item.
E.g. {foo = "bar"} will set `vim.g.foo` to "bar" where
the type of `bar` in the resulting vimscript will be
infered from the type of the value in the `{name = value}`
pair.
