Add a new GPU capability set VIRTIO_GPU_CAPSET_ROCM to support ROCm compute workloads in virtualized environments.
ROCm (Radeon Open Compute) is AMD's open-source software platform for GPU compute and HPC workloads. ID 7 is already used by VIRCL, and gfxstream's rutabaga_gfx has already claimed IDs 7-9 ahead of any spec or kernel header update, so ROCm uses ID 10 to avoid a further collision. A matching virtio-gpu specification change is in progress to register this assignment. Also add the matching VIRTGPU_DRM_CAPSET_ROCM alias in virtgpu_drm.h for consistency with the other capability sets exposed through DRM_IOCTL_VIRTGPU_GET_CAPS.
