`clang-format` version difference will change formatted code

[William-An]

With different clang-format versions between CI and the development machine, the check-format step might fail as clang-format will generate different outputs even with the same .clang-format file.

We can specify clang-format version requirement in CMakeList file maybe?

I was aware of this. The problem is the format should be independent from clang version if a format file is provided, which is we are doing.

I have no idea why we still get inconsistent results.

That's why I call clang format on raid instead of GitHub runners.
