Add a helper to accumulate per-client runtime of all its
exec queues. This is called every time a sched job is finished.
v2:
- Use guc_exec_queue_free_job() and execlist_job_free() to accumulate
runtime when job is finished since xe_sched_job_completed() is not a
notification that job finished.
- Stop trying to update runtime from xe_exec_queue_fini() - that is
redundant and may happen after xef is closed, leading to a
use-after-free
- Do not special case the first timestamp read: the default LRC sets
CTX_TIMESTAMP to zero, so even the first sample should be a valid
one.
- Handle the parallel submission case by multiplying the runtime by
width.
v3: Update comments
