scripts: kernel-doc: make it more compatible with Sphinx 3.x
With Sphinx 3.x, the ".. c:type:" tag was changed to accept either: .. c:type:: typedef-like declaration .. c:type:: name Using it for other types (including functions) don't work anymore. So, there are newer tags for macro, enum, struct, union, and others, which doesn't exist on older versions. Add a check for the Sphinx version and change the produced tags accordingly.
