[vulkan] Fix a few code generation issues QC's int type is named "integer" (didn't feel like changing that right now), so special case it to be "int". Output the parse func name (instead of "fix me"). Output a parse func for enums (needed for arrays of enums (VkDynamicState)).

[vulkan] Use a property list to drive code gen The property list specifies the base structures for which parser code will be generated (along with any structures and enums upon which those structures depend). It also defines option specialized parsers for better control.

[vulkan] Split up vkgen It worked as a proof of concept, but as the code itself needs to be a bit smarter, it would be a lot smarter to break up that code to make it easier to work on the individual parts.
