docs: cdomain.py: extend it to handle new Sphinx 3.x tags
While most of the C domain parsing is done via kernel-doc, some RST files use C domain tags directly. While several of them can be removed for Sphinx < 3.0, due to automarkup.py, and several others that could be converted into kernel-doc markups, changes like that are time-consuming, and may not fit all cases. As we already have the cdomain.py for handing backward compatibility with Sphinx versions below 3.0, let's make it more complete, in order to cover any usage of the newer tags outside kernel-doc. This way, it should be feasible to use the new tags inside the Kernel tree, without losing backward compatibility. This should allow fixing the remaining warnings with the Kernel tags.
