[llvm] [DirectX][ObjectYAML] Fix GCC name conflict in DXContainerYAML.h (PR #199062)

[Vladislav Dzhidzhoev via llvm-commits]

https://github.com/dzhidzhoev created https://github.com/llvm/llvm-project/pull/199062

After https://github.com/llvm/llvm-project/pull/198222, GCC with `-fpermissive` reports an error:
```
llvm/include/llvm/ObjectYAML/DXContainerYAML.h:328:34: error: declaration of ‘std::optional<llvm::DXContainerYAML::CompilerVersion> llvm::DXContainerYAML::Part::CompilerVersion’ changes meaning of ‘CompilerVersion’ [-Wchanges-meaning]
  328 |   std::optional<CompilerVersion> CompilerVersion;
```

Fix that.
