trunk/474b708affd7beacd45145a5b3d011a9d59c6b5c: [ROCm] Guard NCCL one-sided API behind device support (#186888)

Summary

This updates NCCL_HAS_ONE_SIDED_API to require NCCL_HAS_SYMMEM_DEVICE_SUPPORT, matching the existing guard pattern used for NCCL device-side support.

NCCL_HAS_SYMMEM_DEVICE_SUPPORT is not enabled for ROCm builds because nccl_device.h is excluded there. Without this additional guard, ROCm release branches can still compile one-sided NCCL paths that reference device-side support such as NCCLDevCommManager, causing build failures.

A related guard already exists from #186794; this extends the same protection to the one-sided API path after it caused issues on another ROCm branch.

Testing

• Verified the merge conflict is resolved.


• Verified nccl_dev_cap.hpp has no conflict markers.


• Verified git diff --check passes for the changed file.
