[llvm-branch-commits] [DirectX] Use a more consistent pass name for DXILTranslateMetadata (PR #104249)

[Justin Bogner via llvm-branch-commits]

https://github.com/bogner created https://github.com/llvm/llvm-project/pull/104249

This updates the "dxil-metadata-emit" pass flag to be spelled
"dxil-translate-metadata" to better match the pass name.
