js-on-sx: js-loose-eq unwraps Number and Boolean wrappers

js-loose-eq only had a __js_string_value__ unwrap clause, so
Object(1.1) == 1.1 returned false. Added parallel clauses for
__js_number_value__ and __js_boolean_value__ in both directions.
Now new Number(5) == 5, Object(true) == true, etc.
built-ins/Object: 26/50 → 37/50. conformance.sh: 148/148.
