Fix GPU metric tests & cleanup test output

- CLI: Added average_power to display if current_power is empty
    - CLI: fixed PCIe current_speed not displaying GT/s
    - ROCm API: 1.3 & 1.4
                -> commented out setting avg clocks to current clock value
(leave as max uint value, not re-assign; these are not same values)
                    -> commented out setting current_socket_power = average_power
(leave as max uint value, not re-assign; these are not same values)
                    -> For all non-array clocks, placed value in first
                        array[0] to keep outputs consistent
                    (helps xcd calc)
      - ROCm API: rsmi_dev_metrics_curr_gfxclk_get fixed to count
        XCDs using backwards compatible rsmi_dev_gpu_metrics_info_get.
      - ^ Fixes XCD count overall + assigning clock[0] in 1.3 to curr
        freq
      - AMD SMI API: amdsmi_get_gpu_metrics_info() initialized all new
        1.5 metric values for all lower metric tables
      - AMD SMI API: wrapper -> fix is here + returns correct AMD SMI return
      - AMD SMI API: wrapper -> now displays amdsmi return status as
        string in logs
      - gpu_metrics_read.cc -> now has better overview of backwards
        compatible output
      - gpu_metrics_read.cc -> Cleaned up output, added units, and
        display all array output
