Batch update feature gates for 1.22 

Here is a second batch for feature gate updates in 1.22.

- CPUManagerPolicyOptions    kubernetes/kubernetes#101432
- ControllerManagerLeaderMigration  kubernetes/kubernetes#103533
- DynamicKubeletConfig    kubernetes/kubernetes#102966
- EndpointSliceProxying  kubernetes/kubernetes#103451
- EndpointSliceTerminatingCondition  kubernetes/kubernetes#103596
- HugePageStorageMediumSize    kubernetes/kubernetes#99144
- JobTrackingWithFinalizers   kubernetes/kubernetes#98817
  (also tracked in #28841, can rebase).
- ServiceInternalTrafficPolicy  kubernetes/kubernetes#103462
- WindowsEndpointSliceProxying   kubernetes/kubernetes#103451

Some of these needs more detailed documentation.

(e.g. the cloud-controller-manager) in an HA cluster without downtime.
- `CPUManager`: Enable container level CPU affinity support, see
[CPU Management Policies](/docs/tasks/administer-cluster/cpu-management-policies/).
- `CPUManagerPolicyOptions`: Allow fine-tuning of CPUManager policies.
- `CRIContainerLogRotation`: Enable container log rotation for CRI container runtime. The default max size of a log file is 10MB and the
default max number of log files allowed for a container is 5. These values can be configured in the kubelet config.
See the [logging at node level](/docs/concepts/cluster-administration/logging/#logging-at-the-node-level) documentation for more details.

- `IPv6DualStack`: Enable [dual stack](/docs/concepts/services-networking/dual-stack/)
support for IPv6.
- `JobTrackingWithFinalizers`: Enables the tracking of Job completion without
relying on Pods remaining in the cluster indefinitely. Pod finalizers, in
addition to a field in the Job status, allow the Job controller to track
Pods that it didn't account for yet.
- `KubeletConfigFile`: Enable loading kubelet configuration from
a file specified using a config file.
