Libgomp now supports setting OpenMP device capabilities on a per-device basis, rather than just a generic type. This allows finer control, such as enabling unified-shared memory (USM) only for specific devices like integrated GPUs (APUs). The change moves requirement handling back to target.c and improves OpenMP offloading for USM on appropriate hardware.
