LOG: [HLSL][clang][Driver] Fix error when using the option -fcgl in --driver-mode=dxc. (#97001)
When -fcgl is set in --driver-mode=dxc, both -S and -emit-llvm are
currently enabled.
This results in the following error:
```
error: '-S' action ignored; '-emit-llvm' action specified previously.
```
This change fixes the issue by not rendering -S in RenderHLSLOptions.
Additionally, a test has been added to ensure that enabling -fcgl does
not trigger any diagnostics
Fixes #97296
