[libclc] Expose prepare_builtins_* variables in top-level CMakeLists (#149657)

Browse Source 
Fix `libclc/utils/CMakeLists.txt` to expose `prepare_builtins_*`
variables in parent scope. This was a regression introduced in #148815
where the code was moved into subdirectory, and the variables would no
longer be accessible to calls in top-level CMakeLists, resulting in
attempting to build targets with empty command:

```
