drm/xe: Add process name and PID to job timedout message

drm/xe: Add process name and PID to job timedout message

This will be very helpful for Mesa CI, where it uses PID to match
the exacly test that cause timedout/GPU hang and mark that test as
failing.

Also printing the process name as it might be relavant for human
readers.
