Improve error message for passivating bean with a non-passivation-capable interceptor/decorator

The current message reads:

WELD-000072 Managed bean declaring a passivating scope must be passivation capable. Bean: Managed Bean [class org.jboss.weld.tests.contexts.passivating.serialization.InterceptedBean] with qualifiers [@Any @Default]

Although this message is perfectly valid, a more specific error message specifically mentioning the interceptor/decorator would save people time and confusion.
