gpu: nvgpu: Add debugfs wrapper for exposing profilers

Browse Source 
The current debugfs code is completely specific to FIFO's kickoff
profiler. But exposing these debugfs nodes is really a perfectly
generic operation to any given profiler.

Therefore add a generic debugfs interface for exposing profilers.
Any code that implements a profiler can now use a single function
call to export a profiler to the GPU debugfs area.
