Add per-component hostNetwork support for all DaemonSet operands

Previously, only DCGMExporter supported configuring hostNetwork through
the ClusterPolicy CRD. This commit extends hostNetwork support to all
remaining DaemonSet components: Driver, VGPUManager, Toolkit,
DevicePlugin, SandboxDevicePlugin, KataDevicePlugin, DCGM,
NodeStatusExporter, GPUFeatureDiscovery, MIGManager, KataManager,
VFIOManager, CCManager, VGPUDeviceManager, and Validator.

Each component's Spec type now includes an optional HostNetwork *bool
field following the same pattern as DCGMExporterSpec. When enabled, the
controller sets hostNetwork: true and DNSPolicy: ClusterFirstWithHostNet
on the corresponding DaemonSet pod spec.

Changes:
- Add HostNetwork field to 15 component Spec types in ClusterPolicy CRD
- Add applyHostNetworkConfig helper and call it in 17 Transform functions
- Add hostNetwork values and Helm template rendering for all components
- Regenerate deepcopy functions and CRD manifests
- Add unit tests for applyHostNetworkConfig
