https://github.com/ldionne created https://github.com/llvm/llvm-project/pull/74334

This patch runs clang-format on all of libcxx/include and libcxx/src, in accordance with the RFC discussed at [1]. Follow-up patches will format the benchmarks, the test suite and remaining parts of the code. I'm splitting this one into its own patch so the diff is a bit easier to review.

This patch was generated with:

   find libcxx/include libcxx/src -type f | grep -v 'module.modulemap.in' | grep -v 'CMakeLists.txt' | grep -v 'README.txt' | xargs clang-format -i

format the benchmarks, the test suite and remaining parts of the code.
I'm splitting this one into its own patch so the diff is a bit easier
