format-code: enable config-clang-tidy format checking

config-clang-tidy has been introduced as a tool for formatting and
modifying `.clang-tidy` files in a consistent way across the
organization.  All existing `.clang-tidy` files have been reformatted
already with this tool, so enable running in CI to prevent format
regressions.
