Classes in method params can be allowed by method attributes

[spaze]

This is a continuation of the allowInMethodsWithAttributes feature added in 4.3.1.

When you disallow the Event class (with disallowedClasses) and would like to allow it again in a method that has the Attr attribute (see the example code below), the Event class should be allowed even in the method signature. Previously, it was flagged as a disallowed usage (#315)

class Handler
{
    #[Attr]
    public function foo(Event $event) // should be allowed too
    {
        $event = new Event(); // allowed
    }
}
