Backport of #4819 to release-v1.43.
Pairs with the new third-party-cni-plugins image. After the mono-image consolidation, calico/calico no longer ships the upstream CNI plugin binaries baked into /opt/cni/bin, so on platforms that don't pre-populate the host CNI bin dir, install-cni finds nothing to copy and pods depending on host-local, portmap, loopback, tuning, or flannel break.
This adds a cni-plugins init container ahead of install-cni that copies the binaries into a shared emptyDir, which install-cni mounts at /opt/cni/bin. CNI.InstallMode defaults to All; set it to CalicoOnly on hosts that already provide the upstream plugins to skip the init container.
Note: the init container image still needs promoting to quay.io before default installs can pull it.
