Delete Devtools cache reset support for HATEOAS

As of spring-projects/spring-hateoas#854, Spring HATEOAS is not relying
on Objenesis anymore and removed the cache that was being used for it.

This commit removes the support for clearing that cache when running an
application with Devtools enabled.

See gh-16833
