eval: add v:_null_string
Replacement for Vim's test_null_string().
Vim uses it to verify that its codebase handles null strings.
Preparation for the Test_null_list() in patch v8.2.1822.
Use v:_null_string, not non-existent env var, for null string tests.
Mention v:_null_string in id() because id(v:_null_string) returns (nil).
