gpu: nvgpu: IOCTL to set stop_trigger type

Add IOCTL NVGPU_DBG_GPU_IOCTL_SET_NEXT_STOP_TRIGGER_TYPE
to set next stop_trigger type (either single SM or
broadcast to all SMs)

Also, expose below APIs to check and clear broadcast flag:
gk20a_dbg_gpu_broadcast_stop_trigger()
gk20a_dbg_gpu_clear_broadcast_stop_trigger()
