Fix `libclc/utils/CMakeLists.txt` to expose `prepare_builtins_*` variables in parent scope. This was a regression introduced in llvm#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: ``` [1566/1676] cd /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build && -o /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build/clspv--.bc /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build/obj.libclc.dir/clspv--/builtins.opt.clspv--.bc FAILED: clspv--.bc /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build/clspv--.bc cd /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build && -o /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build/clspv--.bc /var/tmp/portage/llvm-core/libclc-22.0.0.9999/work/libclc_build/obj.libclc.dir/clspv--/builtins.opt.clspv--.bc /bin/sh: line 1: -o: command not found ```
