Ettore Di Giacinto 67ff7de374 fix(turboquant): HIP-port the fork's CUDA additions (copy2d 3D-peer + cudaEventCreate) ...

The turboquant fork adds/modifies a few ggml-cuda.cu spots with CUDA APIs that
ggml's HIP/MUSA shim does not provide, breaking the -gpu-rocm-hipblas-turboquant
build. patches/0001-hip-guard-copy2d-peer-fastpath.patch (applied by
apply-patches.sh) ports them:

- Guard ggml_cuda_copy2d_across_devices's 3D-peer copy fast path with
  #if !defined(GGML_USE_HIP) && !defined(GGML_USE_MUSA) so HIP/MUSA fall through
  to the existing cudaMemcpyAsync staging fallback (HIP genuinely lacks
  cudaMemcpy3DPeerAsync, per the fork's own comment).
- Create the device event in ggml_backend_cuda_device_event_new with the
  HIP-aliased cudaEventCreateWithFlags(.., cudaEventDisableTiming) instead of the
  un-aliased plain cudaEventCreate, matching this file's own usage elsewhere.

CUDA builds are unaffected.
