Switch from null terminated arrays to `wcstring_list_t` for lists of special env var names. Rename `list_contains_string` to `contains` and modify the latter interface to not rely on a `#define`. Rename `list_contains_string()` to `contains()` and eliminate the current variadic implementation. Update all callers of the removed version to use the string list version.
