Zebediah Figura 83c67e76ff include: Add basic documentation for vkd3d_types.h. 
This is built on Doxygen. I'm not personally attached to Doxygen, but it was
easy enough to set up and write for, and I've found its compiled HTML to be
reasonably legible.

Note that Doxygen does allow for specifying documentation in external files,
if keeping the documentation out of the header is desired.
