Subject: [PATCH] doxygen: update to 1.9.7 + add documentation

This adds a new subpackage doxygen-doc which contains doxygen's
documentation in PDF and HTML form.

This uses the .repack version of doxygen which contains some fixes,
notably for https://github.com/doxygen/doxygen/issues/10094 and
https://github.com/doxygen/doxygen/issues/10053#10053
