Auto merge of #123918 - DianQK:clang-format, r=Kobzol

Use `clang-format` in `tidy` to check the C++ code style under `llvm-wrapper`

Fixes #123510.

Based on the discussion at https://rust-lang.zulipchat.com/#narrow/stream/233931-t-compiler.2Fmajor-changes/topic/Enable.20.60clang-format.60.20for.20.60rustc.60.20compiler-team.23756/near/443562800, we can use clang-format from pip to achieve the code formatting.
