Parameter type does not propagated to decorator proxy

Because of https://issues.jboss.org/browse/WFLY-11566 we have to add method signature propagation to proxies as well.

After this change org.jboss.weld.tests.builtinBeans.decorator.broken.NonPassivationCapableEventDecoratorTest started to fail.

I have looked at this issue and found that the method...

public org.jboss.weld.tests.builtinBeans.decorator.broken.1966156579$Proxy$_$$_WeldDecoratorProxy.fireAsync(U e
xtends null)

... is generated wrongly (extends null - should be T. The signature is OK in the base class but it's get lost during the proxy generation.

I have looked further and it seemed to me that it may be lost somewhere in
...

org.jboss.weld.annotated.slim.backed.BackedAnnotatedMethod
org.jboss.weld.annotated.slim.backed.BackedAnnotationParameter

... which seem to loose the parameter.
