Issue:
Deprecate the reference pointer helper functions
From @negz comment in: https://github.com/crossplane/crossplane-runtime/pull/754#discussion_r1710367975, copied here for convenience:

> Huh, I actually forgot we had these pointer helpers in runtime.
>
> We usually use https://pkg.go.dev/k8s.io/utils/ptr instead these days. I'd suggest that. We should probably deprecate the ones we have in runtime, but that can happen in a separate PR.
