Remove Controller-Runtime Dependencies from API Types

[robscott]

What happened:
Our API types currently include controller-runtime dependencies.

What you expected to happen:
We should not have a dependency on Controller-Runtime in our API types. For example, look at the equivalent Gateway API file that is fully generated: https://github.com/kubernetes-sigs/gateway-api/blob/aa9679341fdc2cd919a230bf9887416c1881ef2f/apis/v1/zz_generated.register.go#L24-L43
