UPSTREAM: ANDROID: tracing: add power/gpu_work_period

Browse source 
From Android 16 CDD:

  [C-0-13] MUST implement the shell command dumpsys gpu --gpuwork to
  display the aggregated GPU work data returned by the
  power/gpu_work_period kernel tracepoint, or display no data if the
  tracepoint is not supported. The AOSP implementation is
  frameworks/native/services/gpuservice/gpuwork/.

Bug: 457797217
Test: cat /sys/kernel/tracing/events/power/gpu_work_period/format
