Chris Mumford 297e66afc1 Format all files IAW the Google C++ Style Guide. Use clang-format to correct formatting to be in agreement with the [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html). Doing this simplifies the process of accepting changes. Also fixed a few warnings flagged by clang-tidy. PiperOrigin-RevId: 246350737			5 lat temu
