XML config does not apply `request-handler-ref` to `CsrfAuthenticationStrategy`

[sjohnr]

Describe the bug
CsrfBeanDefinitionParser does not apply the value of request-handler-ref to the bean definition of CsrfAuthenticationStrategy.

Note: By contrast, CsrfConfigurer does apply the configured CsrfTokenRequestHandler to the default CsrfAuthenticationStrategy.

Expected behavior
CsrfBeanDefinitionParser applies the value of request-handler-ref to the bean definition of CsrfAuthenticationStrategy.
