docs/vulkan: use hawkmoth instead of doxygen

Use the hawkmoth c:auto* directives to incorporate vulkan documentation.

Convert @param style parameter descriptions to rst info field lists.
Add static stubs for generated headers. Fix a lot of references, in
particular the symbols are now in the Sphinx C domain, not C++
domain. Tweak syntax here and there.
