Remove deprecated endpoint base classes

This deprecates the programming model of extending from base endpoint
class in favor of the `@Endpoint` programming model introduced in
Spring-WS 2.0.

This also removes any reference <sws:marshalling-endpoints/> and
<sws:xpath-endpoints/> that are no longer part of the XSD since 2.0
as well.

Closes gh-1487
