[Feature] Implement KEP-4815 partitionable devices without SharedCounters

[johnahull]

Summary

Implement KEP-4815 partitionable-device support for the Intel resource drivers without relying on SharedCounters.

Current state

The repository enables DRAPartitionableDevices in the test cluster configuration, but the drivers publish ordinary devices and do not emit partitionable capacity (ConsumesCounters/SharedCounters). The QAT E2E code still documents its ConfigMap workaround as temporary until partitionable devices are implemented.

Scope

• Define the partitionable resource model for the affected drivers.
• Publish the required DRA device capacities and consumption data without SharedCounters.
• Replace the QAT ConfigMap allocation workaround.
• Add unit and end-to-end coverage for partial allocations and accounting.
