Add unrooted_must_root lint for enums and structs containing JS<T>, as well as functions with JS<T> in their parameter list
For safe wrappers over JS<T> (eg Temporary<T>) use #[allow(unrooted_must_root)]. For all other types containing a #[must_root] value, annotate the type with #[must_root] to ensure that it is never used unrooted
