This patch I`ve done the following things:

1. run clang-tidy cd builf && python3 ../run_clang_tidy.py -p . -fix
2. format codes

   git ls-files --exclude-standard | grep ".*\(cc\|hh\)$" | xargs clang-format -i -style=file --dump-config 

3. add licence to run_clang_tidy.py and clang-tidy config file

Currently the patch can be built on my macOS(arm Apple clang version 15.0.0) and ubuntu(x64 clang-18) and passes UTs with mkdir build -p && cd build && cmake .. -DBUILD_JAVA=OFF -DCMAKE_BUILD_TYPE=DEBUG -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -DCMAKE_EXPORT_COMPILE_COMMANDS=1 && make -j20 && make test .

@dongjoon-hyun Hi, do you have any suggestions about this patch?

Although I've been monitoring this PR and discussion, there is no other objection for the AS-IS direction including backward compatibility consideration.
