gpu: nvgpu: in-kernel kickoff profiling

Add a debugfs interface to profile the kickoff ioctl
it provides the probability distribution and separates the information
between time spent in: the full ioctl, the kickoff function, the amount
of time spent in job tracking and the amount of time doing pushbuffer
copies
