ROCm SMI Python CLI: Add CU Occupancy to showPids function

The purpose of this patch is to add CU occupancy functionality to showPids
by calling rsmi_compute_process_info_get from the LIB.

Now showPids shows the following information on (KFD compute) processes:
PID, process name, GPU(s), VRAM used, SDMA used, and CU occupancy.
