Update empty method guards to new style with regex (see PR). Used clang-format 18.1.8. New actions to validate code formatting is added. Update .clang-format with disabling of include sorting. It is temporary changes, then include will be sorted. Apply formatting for /src and /tools folder. The files with .hxx,.cxx,.lxx,.h,.pxx,.hpp,*.cpp extensions.
