Remove deprecated webhook.Defaulter/Validator interface assertions

These compile-time assertions reference webhook.Defaulter and
webhook.Validator interfaces that are removed in controller-runtime
v0.21 (OCP 4.20). The assertions are dead code — webhook registration
already uses CustomDefaulter/CustomValidator in internal/webhook/.

Removing them makes the API module forward-compatible with CR v0.21
so that consumers (like openstack-operator) can bump controller-runtime
without needing replace directives for this operator.
