[SWDEV-496693] GPU metrics 1.7

Changes:
    - Added new GPU metrics:
      1) XGMI link status - Up/Down; 1 = up; 0 = down
      2) Graphics clocks below host limit (per XCP)
         accumulators -> used to help calculate a violation status
      3) VRAM max bandwidth at max memory clock
    - Updated rocm-smi --showmetrics to include new metrics.
    Units/values reflect as indicated by driver, may differ
    from AMD SMI or other ROCm SMI interfaces which
    use these fields.
    - N/A fields means the device does not support providing this
    data.
