drm/xe: Change devcoredump functions parameters to xe_sched_job

When devcoredump start to dump the VMs contents it will be necessary
to know the starting addresses of batch buffers of the job that hang.

This information it set in xe_sched_job and xe_sched_job is not easily
acessible from xe_exec_queue, so here changing the parameter, next
patch will append the batch buffer addresses to devcoredump snapshot
capture.

v3:
- update functions documentation to xe_sched_job
