[SWDEV-536953] Fix sets/resets + Align Power Cap Behavior with ROCM_SMI (#456)

Changes:
  - Modified outputputs for amd-smi set/reset when in partitions
    to display error codes
  - Provided some general cleanup for the above ^
----------------------------------------------------
  - Updated  `amd-smi set -o <value>` /  `amd-smi set --power-cap <value>`  command to
    allow setting power cap to values other than 0, provided the current power cap is not 0.
  - Modified power_cap_read_write.cc:
    - Added a check to ensure that the power cap can only be set to non-zero values if the current
      power cap is not 0.
    - Reset the power cap to the original value after the test to maintain state consistency.
