VPP-62 Add a doxy filter to enable vpe.api doc
This makes Doxygen think the API definitions are structs which is close enough to be able to document the API methods. It also has logic to create an indexed API page but that's disabled for now because it duplicates the "brief" text twice in the struct doc. Fixes a minor line numbering issue in filter_c.py.
