kubeadm: only run kube-proxy on architecture consistent nodes

**What this PR does / why we need it**:
Currently `gcr.io/google_containers/kube-proxy-{.Arch}` is not multi-arch image. We should use `affinity` or `nodeSelector` to only run the pods on the nodes with the matching architecture, like what we've done in `kube-dns`. 

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
partial Fixes #64647
