Awesome work, thank you! Two bits of feedback
Migrate the `CIDR` and `IPv6CIDR` of the `ipamTypes.Subnet` struct from `*cidr.CIDR` to `*netip.Prefix` (`cidr.CIDR` is a light wrapper on top of `net.IPNet`). The `CIDR.AvailableIPs()` method is migrated from the `cidr` package to the `azure/api` one as that's the only place where it's used and updated to work with `netip.Prefix` instead of `CIDR`. The `DeepEqual` and `DeepCopy` methods for `ipamTypes.Subnet` are no longer autogenerated as they can't be since the `Subnet` struct now depends on an external `netip.Prefix` type that does not implement those methods.
