873b8d50 - [flang][cuda][NFC] Use NVVM operation for thread syncs (#166999)

[flang][cuda][NFC] Use NVVM operation for thread syncs (#166999) Use the operation introduced in #166698. Also split the test into a new file since `flang/test/Lower/CUDA/cuda-device-proc.cuf` is getting to big. I'm planning to reorganize this file to have better separation of the tests
