* [SWDEV-493274/SWDEV-514998] Add AMD SMI partition tests + Add Guest amd-smi static --partition
Changes:
- Added amd-smi static --partition for guest systems
- Added C++ tests for memory and compute (accelerator) partitions
- Added Python tests for amdsmi_get_gpu_vram_info(),
amdsmi_get_gpu_accelerator_partition_profile_config()
- Updated Python tests for
amdsmi_get_gpu_accelerator_partition_profile()
Now includes more profile and resource detail
- Added amdsmi_get_gpu_xcd_counter();
Tests provided for both C++/Python APIs
- Added AmdSmiVramType & AmdSmiVramVendor: they were missing
python testing required adding.
