How do we use this ?
i tried 
```
> /opt/llvm-git/usr/bin/clang -std=c++23 -stdlib=libc++ -print-library-module-manifest-path
<NOT PRESENT>
```

and 

```
> /opt/llvm-git/usr/bin/clang -std=c++23 -stdlib=libc++ -print-library-module-manifest-path -resource-dir=/opt/llvm-git/usr/lib
<NOT PRESENT>
```
but no manifest path is returned

```
> fd .json /opt/llvm-git/usr/lib
/opt/llvm-git/usr/lib/libc++.modules.json
```
