gpu: nvgpu: vgpu: profiler reservation support

Browse Source 
Support for hwpm reservations in the virtual case:

- Add session ops for checking and setting global and context reservations, and
  releasing reservations
- in the native case, these just update reservation counts and flags
- in the vgpu case, when the reservation count is 0, check with the RM server
  that a reservation is possible: for global reservations, no other guest
  can have a reservation; for context reservations, no other guest can have
  a global reservation
- in the vgpu case, when the reservation count is decremented to 0, notify
  the RM server that the guest no longer has any reservations
