This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Add an automatically-generated "tensorflow.python.platform.build_info…
…" script. The motivation for this script is to provide better tools for diagnosing load-time errors (such as the ones that plague the Windows build due to DLL issues). Note that the script is intended to be self-contained, so that it is possible to import it without loading the entire TensorFlow runtime. This generated script currently contains a single symbol, `is_cuda_build`, which records whether the build has GPU support or not. PiperOrigin-RevId: 168471034
