Move `@LocalServerPort` and `@LocalManagementServerPort` back to
`spring-boot-test`. The should help reduce upgrade pain since these
annotations are fairly commonly used. It also removes the need for
depending on `spring-boot-webserver-test`.
This is slight compromise with the module structure, since the
web-server module usually contributes the properties referenced
by the annotations.
