drm/amdgpu: give each kernel job a unique id
Userspace jobs have drm_file.client_id as a unique identifier
as job's owners. For kernel jobs, we can allocate arbitrary
values - the risk of overlap with userspace ids is small (given
that it's a u64 value).
In the unlikely case the overlap happens, it'll only impact
trace events.
Since this ID is traced in the gpu_scheduler trace events, this
allows to determine the source of each job sent to the hardware.
To make grepping easier, the IDs are defined as they will appear
in the trace output.
