[TIMOB-18405] HAL: Create helper functions/macros for typical argument list type checking/casting in js_* bridge methods

JSValue UIModule::js_createSlider(const std::vector<JSValue>& arguments, JSObject& this_object)
{
	JSObject parameters = get_context().CreateObject();
	if (arguments.size() >= 1) {
		const auto _0 = arguments.at(0);
		TITANIUM_ASSERT(_0.IsObject());
		parameters = _0;
	}
	return createSlider(parameters, this_object);
}

we seem to do this pattern a lot where we pull something out of a argument list, cast it, check the type via assertion, etc. this is a good place to come up with either an inlined helper function or a macro. makes the code more readable and has the advantage for developers to ensure we have a very common pattern for how to do this logic.
