[why] xrt-smi JSON report showed "id": "00000000-0000-0000-0000-000000000000" for all Ryzen/NPU devices (Phoenix, Strix, Strix2, StrixH, Krackan, Medusa, Soundwave). The root cause: rom_time_since_epoch returns a hardcoded 0 for Ryzen devices instead of throwing, so the existing Alveo 1RP path silently set id="0". No Ryzen-specific path existed, leaving every NPU device with an identical, non-unique identifier in the JSON output. [how] Extract device ID generation into a dedicated get_device_id() function in XBUtilities.cpp. For Ryzen/NPU devices, derive the UUID from PCIe BDF (domain, bus, device, function) using the same memcpy byte-packing as hip_device_get_uuid(), ensuring the xrt-smi id is consistent with the HIP UUID API. Alveo 2RP (xclbin logic UUID) and 1RP (ROM timestamp) paths are retained as fallbacks for non-Ryzen devices. AIESW-29257

Replace C-style byte array and magic number indices with xuid_t + std::apply fold, eliminating all cppcoreguidelines-avoid-magic-numbers and cppcoreguidelines-avoid-c-arrays warnings. AIESW-29257
