Migrate cpumanager to use checkpointing manager **What this PR does / why we need it**: This PR migrates `cpumanager` to use new kubelet level node checkpointing feature (#56040) to decrease code redundancy and improve consistency. **Which issue(s) this PR fixes**: Fixes #58339 **Notes**: At point of submitting PR the most straightforward approach was used - `state_checkpoint` implementation of `State` interface was added. However, with checkpointing implementation there might be no point to keep `State` interface and just use single implementation with checkpoint backend and in case of different backend than filestore needed just supply `cpumanager` with custom `CheckpointManager` implementation. /kind feature /sig node cc @flyingcougar @ConnorDoyle
