gpu: nvgpu: add cycle stats to debugger node

Browse Source 
Add NVGPU_DBG_GPU_IOCTL_CYCLE_STATS to debugger node, to
install/uninstall a buffer for cycle stats.

Add NVGPU_DBG_GPU_IOCTL_CYCLE_STATS_SNAPSHOT to debugger
node, to attach/flush/detach a buffer for Mode-E streamout.

Those ioctls will apply to the first channel in the debug session.
