Add support for XPU performance counter

damian-szw requested to merge dev/dszwicht/xpu-perf-counter into xpu

This PR introduces performance counters for the XPU device. It uses the Level Zero metric API to track device metrics on a time-based schedule: data is gathered internally and processed (summed) when a getPerfCounter() request is made. The following settings allow you to configure collection intervals and timeouts:

  • COLLECTOR_NOTIFY_INTERVAL: The number of collected reports after which a notification event is triggered.
  • COLLECTOR_SAMPLING_PERIOD_NS: The sampling period (in nanoseconds) for the metrics streamer.
  • COLLECTOR_DELAY_NS: The synchronization timeout (in nanoseconds).
