[SWDEV-518325/SWDEV-518320/SWDEV-443309] Fix Partition Enumeration

* Changes:
  - Updates to DRM renderD* / card* pathing for partition devices
  - Now use KFD to discover AMD devices and populate accordingly
    Device MUST have an accessible KFD node (via cgroups)
  - Updated several ROCm SMI CLI outputs to handle SYSFS files
    which are not accessible on partition nodes
  - Added a new method to help get card/drm info
    (rsmi_dev_device_identifiers_get) from ROCm SMI
