Currently the PR formatting job only runs clang-format. There isn't a lot of utility in running it if there aren't any C/C++ changes as there will be nothing to format. This isn't super noisy currently as the job doesn't fail if there aren't any C/C++ changes, but it's a bit of a waste.

In addition, this patch names the code formatting job "Check C++ Formatting" to make it clear that this job only checks C/C++ formatting rather than Python formatting/other languages.
