There are some general improvements can be made:

- Create a separate test file `use-cpp-style-comments-doxygen.cpp` and leave `use-cpp-style-comments.cpp` as it was before. With this, we can make sure that check runs good both with and without option.

- Add documentation about option `ExcludeDoxygenStyleComments` in clang-tools-extra/docs/clang-tidy/checks/readability/use-cpp-style-comments.rst. You can use others docs with described options as reference.
