Add CL and CMD into to pdb debug info

Partial fix for https://github.com/rust-lang/rust/issues/96475

The Arg0 and CommandLineArgs of the MCTargetOptions cpp class are not set within bb548f9645/compiler/rustc_llvm/llvm-wrapper/PassWrapper.cpp (L378)

This causes LLVM to not  neither output any compiler path (cl) nor the arguments that were used when invoking it (cmd) in the PDB file.

This fix adds the missing information to the target machine so LLVM can use it.
