✨ Add AnnotatedEventRecorderProvider interface

[adri1197]

Adds support for creating event recorders that can attach custom annotations to events,
mirroring the AnnotatedEventf capability recently added to client-go/tools/events
(see kubernetes/kubernetes#138103).

This introduces a new AnnotatedEventRecorderProvider interface in pkg/recorder rather
than adding a method to the existing Provider interface, so this is a backwards-compatible
change. Consumers can type-assert the manager/cluster to access the new functionality:

if p, ok := mgr.(recorder.AnnotatedEventRecorderProvider); ok {
    rec := p.GetAnnotatedEventRecorder("my-controller")
    rec.AnnotatedEventf(obj, nil, map[string]string{"key": "value"}, corev1.EventTypeNormal, "Reason", "Action", "Note")
}

Changes:

• Added AnnotatedEventRecorderProvider interface in pkg/recorder
• Implemented GetAnnotatedEventRecorder on the internal recorder Provider
• Implemented AnnotatedEventf on lazyRecorder
• Added GetAnnotatedEventRecorder on cluster and controllerManager (concrete types only, no interface changes)
• Added unit and integration tests

Hi @adri1197. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
