gpu: nvgpu: Re-factor perfmon unit

Browse Source 
- Move the perfmon unit source code to common/pmu/perfmon/ folder
- Separate perfmon unit headers under include/nvgpu/pmu/pmu_perfmon.h
- Make a new structure: nvgpu_pmu_perfmon for perfmon unit
- This new struct combines all perfmon unit variables like
  perfmon_query, perfmon_ready etc. into one
  structure as a part of perfmon unit refactoring.
- Use pmu_perfmon struct to access all perfmon variables.
- Eg: pmu->pmu_perfmon->perfmon_query, pmu->pmu_perfmon->perfmon_ready
  and so on.
