Add GPU Compute Error tracking to API

[alferz]

This commit will add a tracking mechanism to log GPU Compute Errors by thread. This could be useful for automated scripts/monitoring setups where keeping track and alerting on GPU Compute Errors is an early indicator of impending failure. API output will include a new "results" member as shown below where the object name is equal to the thread with the failure, and the object value represents the number of failures.

"gpuComputeErrors": { "1": 1, "2": 2, "3": 1, "4": 2, "5": 1, "6": 4, "7": 4 }
