Ensure addon-resizer 1.8.11 only effective at arch amd64. (#8144)

* Ensure addon-resizer 1.8.11 only effective at arch amd64.

k8s.gcr.io/addon-resizer:1.8.11 returns the amd64 image which is not executable at arm64.

Disable addon-resizer when the platform is not amd64.

When metrics-server upgrade and use addon-resizer:2.3, then revert this
commit and `image_arch` will determine the `addon_resizer_image_tag`.

* Add metrics_server_resizer architectures check
