Patryk Wrobel e4d56cde21 Detect GPU hangs in blocking enqueue handler calls
This change introduces detection of GPU hangs in blocking
calls to enqueueHandler() function. Moreover, usages of
this function template have been revised and adjusted to
check the exit code. Furthermore, enqueueBlit() and
dispatchBcsOrGpgpuEnqueue() functions returns value now.
ULTs have been added to cover new cases.
