From: Dominik Grzegorzek <dominik.grzegor...@intel.com>
Inform debugger about creation and destruction of exec_queues.
1) Use user engine class types instead of internal xe_engine_class enum
in exec_queue event.
2) During discovery do not advertise every execqueue created, only ones
with class render or compute.
v2: - Only track long running queues
- Checkpatch (Tilak)
v3: __counted_by added
