LibJS+LibWeb: Add JS::Object::inherits(class_name)
To allow implementing the DOM class hierarchy in JS bindings, this patch adds an inherits() function that can be used to ask an Object if it inherits from a specific C++ class (by name). The necessary overrides are baked into each Object subclass by the new JS_OBJECT macro, which works similarly to C_OBJECT in LibCore. Thanks to @Dexesttp for suggesting this approach. :^)
