5753b3f5 - [AMDGPU] Preserve metadata in all barrier lowering paths (#191916)

[AMDGPU] Preserve metadata in all barrier lowering paths (#191916) Extend copyMetadata to every call-to-call replacement in AMDGPULowerIntrinsics, not just the single-wave s_barrier → wave_barrier path. This covers: - s_cluster_barrier → wave_barrier (single-wave) - s_cluster_barrier → signal_isfirst + wait + signal + wait (multi-wave) - s_barrier → signal + wait (split barriers) Add GFX11 and GFX12 RUN lines and test functions for all lowering paths to verify metadata preservation.
