Fixes Vulkan on non-cuda GPUs & adds Pytorch 2.5+ Intel XPU support Fixes Genesis-Embodied-AI#274 Merges the logic of get_gpu_device() and get_cpu_device() to handle device selection in a single place. If a specific backend is requested, this request is honored. The vulkan backend will use intel's pytorch xps device if available, reducing cross-device data transfer. The `gpu` backend will - default to `cuda` when available, - resolve to `mps` on macOS - or fallback to `vulkan`.
