Introduce a heartbeat-based Timeout Detection and Recovery (TDR) mechanism. The enhancement aims to improve the reliability of device hang detection by monitoring heartbeat updates. Each progressing inference will update heartbeat counter allowing driver to monitor its progression. Limit maximum number of reschedules when heartbeat indicates progression to 30. This increases the maximum running time of single inference to about 60 seconds. The heartbeat mechanism provides a more robust method for detecting device hangs, potentially reducing false positive recoveries due to long running inferences.
