The previous internal fcntl implementation modified errno directly, this patch fixes that. This patch also moves open and close into OSUtil since they are used in multiple places. There are more places that need similar cleanup but only got comments in this patch to keep it relatively reviewable. Related to: https://github.com/llvm/llvm-project/issues/143937
