[Track] Crossplane KCL Provider

### What problem are you facing?
I'm wondering if a KCL Crossplane Provider would be beneficial as well, similar to the Helm provider [https://marketplace.upbound.io/providers/crossplane-contrib/provider-helm/v0.18.1]. This would allow more direct access to Kubernetes resources such as Secrets which would be useful for pull secrets to access KCL modules that exists in OCI registries, Git, etc.

### How could this Function help solve your problem?
I think the KCL Function is great and I believe if there was a KCL Provider to accompany it in order to leverage external KCL modules, it would for sure be a very powerful combination.
