[SWDEV-391036 + SWDEV-392933] Fixes for VoltRead and ComputePart.

Updates:
    * VoltRead - needed to properly send out RSMI_STATUS_NOT_SUPPORTED
      when device does not have voltage hwmon files
    * ComputePart. - test failure was likely caused due to EvtNotif
      causing conflicts (unknown exactly why). Test passes when
      moving it ahead of the event notifier. Both API calls may have
      a system resource issue, TBD.
    * rocm_smi_example - now indicates when an API call
      returns RSMI_STATUS_NOT_SUPPORTED or
      RSMI_STATUS_NOT_YET_IMPLEMENTED. Allows example to fully complete
      on systems which may not provide support for all API calls.
