this pr adds a rocm build for cv-utils

same change as causal-conv1d in #1319: the rocm backend, rocm = "2.10" stable abi and a cpp-rocm kernel with the same sources and activation archs, and stable_utils.h picks the hip runtime under USE_ROCM. the kernels have no warp intrinsics and nms already uses 64 bit masks, so no kernel changes. the triton functions from #1182 run on rocm as is

built all rocm variants (rocm70, rocm71, rocm714, rocm72, rocm100) and ran the tests on mi300x (gfx942) with torch 2.10.0+rocm7.0, 2.12.1+rocm7.1 and 2.14.1+rocm7.2, 136 pass on each (4 skipped, they need two gpus). generic_nms keeps the same boxes as torchvision.ops.nms on rocm at 1k, 5k and 20k boxes and is within 4% of its speed

note: this lands in v2, sam3 video still loads version=1 so transformers needs to bump that before it picks up the rocm build. no version bump here since this only adds a backend

*keeping as draft until ci support rocm

• feat: run rocm kernel tests on the amd mi300 runners #1313
