CachedIntrospectionResults should use BeanInfoFactory when introspecting implemented interfaces [SPR-16322] #20869

#18772 updated CachedIntrospectionResults to explicitly introspect implemented interfaces (for Java 8 default methods), however it directly calls Introspector.getBeanInfo and I believe it should probably try the BeanInfoFactory implementations first, in case a custom introspection method is being used.

It's also possible to skip the Serializable interface and stop when Object is reached (rather than null).

Affects: 5.0.2

I've applied a fresh implementation of these points, with a common ClassUtils.isJavaLanguageInterface delegate shared with Conventions where not only Serializable but also Externalizable, Cloneable and Comparable are being ignored.
