gpu: nvgpu: Add a generic profiler

Browse Source 
Add a generic profiler based on the channel kickoff profiler. This
aims to provide a mechanism to allow engineers to (more) easily profile
arbitrary software paths within nvgpu.

Usage of this profiler is still primarily through debugfs. Next up is
a generic debugfs interface for this profiler in the Linux code.

The end goal for this is to profile the recovery code and generate
interesting statistics.
