LOG: [LLDB] Remove C++ language runtime dependency of Clang expression parser (#185450)

From
https://github.com/llvm/llvm-project/pull/169225#issuecomment-4024377289:
There was a dependency cycle involving the C++ language runtime:
```
  //lldb/source/Plugins/TypeSystem/Clang:Clang ->
  //lldb/source/Plugins/ExpressionParser/Clang:Clang ->
  //lldb/source/Plugins/LanguageRuntime/CPlusPlus:CPlusPlus ->
  //lldb/source/Plugins/TypeSystem/Clang:Clang
```

`ExpressionParserClang` doesn't need to depend on the C++ language
runtime. It only included a file, but didn't use it. This PR removes
that dependency.

Added:
