gpu: nvgpu: cyclestats mode E snapshots support
That is a kernel supporting code for cyclestats mode E.
Cyclestats mode E implemented following Windows-design in user-space
and required the following operations to be implemented:
- attach a client for shared hardware buffer of device
- detach client from shared hardware buffer
- flush means copy of available data from hardware buffer to private
client buffers according to perfmon IDs assigned for clients
- perfmon IDs management for user-space clients
- a NVGPU_GPU_FLAGS_SUPPORT_CYCLE_STATS_SNAPSHOT capability added
