This patch adds support for comment fontification using the doxygen parser:
https://github.com/tree-sitter-grammars/tree-sitter-doxygen

This is the same parser used by nvim treesitter and seems to be quite stable.
The attached screenshot shows the result.
This patch also works with emacs 31.

Thanks, I installed this on the master branch.

The code needed a minor fix to not show a warning if the Doxygen
grammar is not available.  Also, please note the changes I made in the
style of the commit log messages (mainly showing the entries for the
same file together, not with a separate "* lisp/..." file-name entry),
and try to follow this style in the future.

With that, I'm closing this bug.
