drm/amdgpu/userq: add a detect and reset callback

Browse Source 
Add a detect and reset callback and add the implementation
for mes.  The callback will detect all hung queues of a
particular ip type (e.g., GFX or compute or SDMA) and
reset them.

v2: increase reset counter and set fence force completion
v3: Removed userq_mutex in mes_userq_detect_and_reset since the driver holds it when calling
