accel/ivpu: Share NPU busy time in sysfs
The driver tracks the time spent by NPU executing jobs
and shares it through sysfs `npu_busy_time_us` file.
It can be then used by user space applications to monitor device
utilization.
NPU is considered 'busy' starting with a first job submitted
to firmware and ending when there is no more jobs pending/executing.
