Add QJSValue::callWithInstance() function

With the deprecated call() overload, it was confusing what the first
argument was (the this-object or an actual argument passed to the
function). Introduce a dedicated function for the
"explicit this-object" case. This makes code more readable, and
eliminates the need to pass a "dummy" this-object to call() in the
quite common case where you don't care about the this-object.
